Concrete hardening accelerator / Liquid glass

Where is silicate glue most often used?

The scope of use of silicate glue is incredibly broad, but construction can still be called the main industry. Waterproofing the foundation with liquid glass will protect the base of the structure from getting wet. This material serves as an excellent additive for concrete, which improves the quality of the mixture and reduces its cost and consumption. You can add silicate glue to the mortar used for laying stoves and fireplaces. With its help, waterproof plaster is obtained.

Foundation waterproofing with liquid glass

Liquid glass has found its application even in such complex activities as waterproofing wells and swimming pools. It reliably fills all the pores in concrete and protects it from the negative effects of moisture and air. The material is also sometimes used when laying PVC slabs and linoleum. It is worth saying that the use of liquid glass is not limited to the construction area. Due to its low cost, many people use such a popular material even at home. Various putties are prepared from it and used to treat cracks and pipe joints. They cover fabrics and other materials, thereby giving them fire-resistant properties. It should be borne in mind that after applying this composition, a protective film is formed on the surface, on which neither paint nor plaster adheres.

Surprisingly, this material is used not only to improve the properties of concrete, it is also popular among gardeners. This composition is used to treat tree cuts, protecting the plant from harmful bacteria.

Description and properties of liquid glass

Liquid glass for concrete , like regular glass, is colorless, slightly yellowish or greenish. The solution contains water. Otherwise, glass would not be liquid. When moisture evaporates, it leaves only silicates, which set into a solid mass. In the closed container we see a viscous adhesive solution. This is what they call silicate glue.

In chemistry, silicates are substances containing a SiO2 fragment in the formula, that is, silicon dioxide. It is used to make not only ordinary glass, but also crystal. There is also a natural version - the mineral quartz.

Its colorless variety is called rock crystal. Stone crystals sparkle, just like man-made ones in chandeliers and glasses. This is because the basis of the materials is the same. Rock crystal crystals, of course, are not allowed on man-made glass. Jewelry quality material. They take sand - crushed quartz, destroyed by winds and waters.

Remembering the properties of ordinary glass and crystal. They are waterproof. The secret is in the density of the material. It has no pores, that is, passages for moisture. Otherwise, window panes would expand in winter.

Water that penetrated the pores would turn into ice, bursting the material. The same thing happens with concrete. It is not 100% resistant to the damaging effects of water because it has pores.

It is not for nothing that foundations are usually covered with waterproofing. Treating concrete with liquid glass is one of the methods of protecting artificial stone from moisture. We’ll talk about the nuances of the technology in the chapter “Proportions and Application”.

The density of liquid glass before solidification is 1.4 grams per cubic centimeter. This is 0.4 grams more than water. Accordingly, liquid glass coating is initially gel-like.

The consistency is reminiscent of confectionery molasses. The material is endowed with the same internal radiation and ductility. Most stones have a density of 2.5-3.5 grams per cubic centimeter.

Like most gel-like substances, liquid glass exhibits astringent properties. It is no coincidence that the material is called glue. Unlike most, it is inorganic, meaning 100% mineral. Other adhesives usually contain organics such as petroleum products, rubbers and silicones.

The chemical composition of liquid glass indicates its high alkalinity, as well as its colloidal nature, that is, the presence of a suspension of solid particles in the solution. This partly determines the use of liquid glass .

It is a successful component of chemical cleaners. We are talking about ordinary detergents. However, the focus of the article is on the use of silicate adhesive in concrete. Therefore, we will not delve into the jungle of glass use in the chemical industry. Let's study better the types of glue.

Application areas of liquid glass

Liquid glass has gained a very wide range of applications. It has already been mentioned that the main direction is waterproofing various sections of the building and its utilities.

Liquid glass has proven its importance and effectiveness as a reliable waterproofing material

Solutions in a diluted state are used as a primer when preparing concrete floors for painting. When building a prefabricated foundation, liquid glass is added to the masonry mortar. Or it can be used to perform surface impregnating waterproofing of masonry joints after the construction of walls.

Waterproofing the basement floor with liquid glass.

Such effective waterproofing is widely in demand when constructing wells, swimming pools, other artificial reservoirs, cellars, garage floors and inspection pits. Liquid glass will help when concreting paths and pouring blind areas of houses and garages on individual plots. Silicate glue is also added to the solution when laying stoves. Liquid glass treatment will be useful when building structures that will be in contact with aggressive substances or high temperatures. Similar silicate compositions are also used in the manufacture of moisture-resistant and acid-resistant concrete or fire-resistant bricks.

Concrete produced with the addition of liquid glass no longer requires additional waterproofing. It is also used as a mortar in the construction of structures that require increased fire resistance.

In addition, a silicate composition is added to concrete if it is necessary to reduce the time it takes to set and gain strength. True, if the solution is prepared for pouring the foundation, then liquid glass is not added to it.

There are many more areas in which silicate composition can be used:

Since liquid glass perfectly protects metal from corrosion, it is often used to cover metal structures, and even car bodies. Using liquid glass, tiles made of polyvinyl chloride can be glued to the wall, and linoleum or carpet can be glued to concrete floors. The silicate composition is also suitable for wood processing. This is done to protect it from moisture and ultraviolet radiation, as well as various pests. Another area of ​​use for this composition is gardening. When pruning fruit trees in spring, cover the sections with liquid glue. It is known that it is an excellent antiseptic that prevents the penetration of microorganisms and harmful insects into unprotected wood after pruning.

Considering the versatile use of liquid glass, it can be called a universal material.

Liquid glass is often used in residential renovations, but many people are poorly aware of the areas of its use, which reduces the technological prospects of repair operations. Let's take a closer look at the use of liquid glass, which will allow you to perform a significant amount of work more productively and efficiently.

So, the material is used for -

1. Preparation of an insulating primer,
2. Production of refractory mortar for laying stoves,
3. Production of surface impregnation for wooden structures.

The primer is used for waterproofing needs and is prepared as follows: for 1 kg of cement, take the same mass fraction of liquid glass and water, and first, using a mixer, mix the cement with water to a well-flowing consistency, after which glass is added to the composition. The quality is determined by the speed of hardening of the primer; its optimal setting time is 20-25 minutes.

When laying stoves and fireplaces, a standard cement-sand mortar is first prepared at the rate of 1 part cement to 3 parts sand, and then liquid glass is added to the masonry composition, which increases the fire-resistant characteristics of the masonry. As a percentage, liquid glass is added to the sand-cement mortar up to 20% of the total mass of the solution. We also note that you should not mix a lot of solution, since its working consistency does not exceed 1-1.5 hours. When using such a mixture, plastering of the stove is carried out no earlier than 73 hours after completion of masonry work.

If it is necessary to impregnate wooden structures, take 1 liter of water and add 350-400 grams of liquid glass mass to it, with constant stirring. The surface of the wood is treated in several layers, and the impregnation is applied with a brush at an interval of 2-4 hours (minimum). This treatment will reliably protect the wood from fungus and mold. In addition, a solution based on liquid glass is often used when wanting to get rid of mold and mildew on plastered and concrete surfaces.

Waterproofing of wells and pools

Waterproofing with liquid glass may involve work in the area of ​​wells and swimming pools. The composition is suitable for external and internal waterproofing. In the latter case, the mixture is applied in several layers to the walls and floor of the pool. You must first process all the recesses and joints. This approach allows for excellent sealing.

When carrying out external work, liquid glass acts as a component of concrete and reliably protects the pool from the effects of groundwater, ensuring the strength of the base. Waterproofing wells with liquid glass involves preparing a mixture of liquid glass, cement and sand, which are combined in equal parts. The resulting solution should be used to treat joints and seams, and then the rest of the surface. In order to achieve a greater effect, the walls of the well are first coated with liquid glass.

What exactly is liquid glass?

It is a mixture of water with sodium or potassium silicate. Glass is added in the production of bricks or concrete buildings, which will be used in aggressive acidic areas. In the household area, it is added to increase the strength of the product. There are cases when cement and liquid glass, the proportions of which were previously carefully calculated, are needed for the speedy drying of any building. The glass looks like a thick yellow liquid. It can be purchased in stores in special containers. The main thing is that the use of glass with cement is justified as a result. After all, cement, and then concrete, are the main components in construction, and therefore their components, especially additional ones, must be treated with special attention. For example, concrete for the base of a building must have some properties, but this material for finishing work must have completely different properties. It also happens that construction needs to be completed in a very short time, and each additive can affect the quality of the building material, both positively and negatively.

Tips at work

To use liquid glass correctly, use the advice of professionals.

Before applying the composition to the surface, it must be diluted with water in the following proportions: per 100 grams of powder 200 grams of water. The product consumption will be 300 g of the mixture per “square”. Waterproofing using the above composition is carried out on concrete walls that have unevenness, as well as on vertical surfaces with weathered plaster. To prepare a composition from liquid glass and concrete, observe the following proportions: 1: 10. Be sure to wear special protective clothing and other accessories while working.

Step-by-step use of the composition as waterproofing:

the floor, foundation or any other surface must be cleaned and dried; the product is applied using a brush or roller; the second layer of the product is applied after half an hour; apply the composition carefully and evenly, avoiding the formation of gaps; next you need to prepare a protective layer, for the preparation of which sand and cement, while liquid glass is added to the mixture, taking into account the proportion of 1: 1; the mixture must be thoroughly mixed and applied to the surface as soon as possible, re-application is not necessary; stirring constantly, the composition is applied to the base using a spatula.

Before using the product, carefully inspect it for lumps and various foreign impurities. Also pay attention to the expiration date of the composition.

Let's look at how to use the solution to treat the foundation.

As in the first case, it is necessary to clean the surface being treated. It is advisable to sand the surface with sandpaper. To apply the composition evenly, use a standard construction roller. After 30 minutes, apply a second layer and, if necessary, a third.

Note: for insulation, use mineral wool or regular polystyrene foam.

PRODUCTION HARDENER FOR LIQUID GLASS

PRODUCTION HARDENER FOR LIQUID GLASS AND

LIQUID GLASS COMPOSITE MIXTURES

Purpose. Powdered liquid glass hardener (POZhS) is intended for physical and chemical curing (solidification) of aqueous solutions of liquid glass and liquid glass composite mixtures when used in various industrial technologies.

In particular, software is used in the foundry industry in the manufacture of molds and cores from self-hardening molding and core mixtures, in the manufacture of combined and single shells in investment casting, in construction to regulate the rate of hardening of liquid glass additives in concrete, cement plaster mortars, cement products , in the oil and gas industry when using liquid glass as drilling fluids, blockers of water filtration of oil and gas wells, water repellents for soil and concrete fencing of water basins and cement products, in road construction for the silicification of support pads of asphalt concrete and cement concrete highways and country roads.

The essence of the physical and chemical effect of a powder hardener on the process of hardening of aqueous solutions of liquid glass and composite mixtures based on it.

The primary process when mixing a powder hardener with liquid glass or mixtures based on it is the physical adsorption of an aqueous solvent on the particles of the hardener powder. As a result, the viscosity of the liquid glass solution and mixtures increases slightly, depending on the amount of the introduced hardener.

For some technologies this is a positive phenomenon, for example in the manufacture of casting molds and cores from liquid glass mixtures, as it helps to increase the density of the mixture and, consequently, the raw strength of the casting mold or core.

For other technologies, this phenomenon may deteriorate the required properties of liquid glass solutions and mixtures, for example, for the preparation and injection of liquid-moving self-hardening suspensions during the treatment of oil and gas wells. In these cases, this disadvantage is adequately eliminated by the use of small additions of surfactants, such as alkali lignin.

The secondary process is the chemical interaction of the hardener with liquid glass, as a result of which liquid glass and mixtures based on it pass from a liquid-moving state into a stationary, so-called coagulated state. This moment is defined as the process of setting of liquid glass, in which, as a result of chemical ion exchange of the hardener substance with colloidal particles of the liquid glass solution, a massive release from the solution (coagulation) of the solid phase occurs in the form of coagulated silica particles. At the same time, the coagulated system is characterized by relatively low strength and is easily destroyed under mechanical stress.

After this, the third period of the interaction process occurs, which consists of the formation of sodium hydrosilicates in sodium liquid glass or potassium silicates in potassium liquid glass in the coagulated system. As a result of this, the coagulated system will acquire high strength and irreversible water resistance, which is important for many known technologies using liquid glass.

The study found that only powdered inorganic hardener, for example, based on calcium silicates and aluminum chlorides, ensures the formation of an irreversible hydroresistant coagulum in mixtures based on liquid glass. Liquid organic hardeners do not ensure the formation of hydroresistant structures of coagulated systems based on liquid glass. Therefore, where high hydrostability of coagulated systems based on liquid glass is required, it is necessary to use powdered inorganic hardeners.

Brands of hardeners differ in their activity on the rate of curing of liquid glass in the form of the following brands: POBD - fast-acting powder hardener; POSD – medium action powder hardener; POMD is a slow action powder hardener.

The specified brands of hardeners must comply with the standards specified in the table according to TU 1257-…………….

Table.

Technical standards for powder hardeners

When ordering a powder hardener, you will receive the full text of the technical specifications (TS), instructions for the use of liquid glass compositions with hardener additives, depending on the intended technological application.

Wells

Waterproofing a well with liquid glass can be carried out both at the stage of its construction and when it is already filled with water.

However, it should be remembered that if the well rings are poorly fastened, then the use of liquid glass will not help. Therefore, you first need to secure the rings well together with metal brackets.

After this, jute, hemp or linen rope is impregnated with a solution of liquid glass and seams are laid between the rings. The top of the seam is covered with another layer of cement or liquid glass. Silicate glue can withstand high water pressure and does not respond to temperature changes.

Using a solution of liquid glass and cement, you can seal small cracks. This solution sets very quickly. But in the case of a large leak, such repairs do not make sense.

Types of liquid glass

The classification of liquid glass is related to its composition. In any version there is silicon dioxide, or simply silica. The second part of the formula is the metal oxide. This metal is the “salt” of glass. So, there are:

• Sodium liquid glass. It is denser than the others. For every cubic centimeter of material there can be 1.6 grams of mass. The silicate module of the substance does not exceed 3.5 units. Modulus refers to the ratio of silicon dioxide to sodium oxide. When their mixture hardens, the glass glares. This is a distinctive property of sodium material. Due to glare, it is rejected when painting surfaces. On the other hand, soda glass has exceptional adhesiveness. In everyday life, it is used to hold together cracked aquariums and heal damage to trees. Sodium glue is used to cover pipe connections and plumbing fixtures.

• Potassium liquid glass. Its density does not exceed 1.4 grams per cubic centimeter, and can be as high as 1.25 grams. The silicate modulus of potassium glue is also lower than that of sodium glue. The frozen composition does not glare. Hence the widespread use in silicate paints. However, if you fasten the seam with a potassium compound, the layer becomes loose. This reduces the material's market share. It is further reduced by the high cost of potassium glue. Sodium is more profitable.

• Mixed glass. In it two metals meet. Trying to achieve the ideal, manufacturers mix potassium and sodium glues in different proportions. The characteristics of the final substance are floating.

Sodium and potassium liquid glasses are regulated by the regulatory and technical framework. For other types of glue, temporary technical specifications are issued, usually within one or several enterprises. They create pilot batches of glass, experimenting with their own products. So, in addition to sodium and potassium compounds, there are:

• Lithium. The silicate modulus of the adhesive is 2.8. The composition is distinguished by its ability to thermoregulate. Therefore, lithium glass is used as a car coating. Due to spraying, a balance is established between the energy released by the internal sources of the machine and absorbed by it from the outside.
• Ammonium. They contain quaternary ammonium. It belongs to hydrocarbon radicals and is distinguished by its ability to dissolve repeatedly in water after drying the gel. Such liquid glass for waterproofing concrete . The silicate seized in the pores of the foundation will dissolve in the first rain. However, for high-modulus powders, compositions with ammonium are just the thing. The glass is highly durable. True, in addition to water, the material is sensitive to temperature changes. The cost of glass is also a deterrent.

Ammonium is organic. Its specific gravity in liquid glass is low. Such compounds are called polysilicates. Outside of Russia, ammonium and lithium mixtures are produced on an industrial scale, regulated by state documentation, like sodium-potassium mixtures.

Therefore, when purchasing foreign products, you are faced with a wide choice. The silicate module of the gels alone “jumps” in the range from 2.4 to 3.7 units. For domestic adhesives, the frames are narrowed to 2.6-3.5.

In addition to the main composition, liquid glasses may contain impurities:

-magnesium oxide

-aluminium oxide

-iron oxide

-calcium oxide

-sulfur oxide

These impurities are contaminants that get into the glue during the production stages. Most often, oxides are present in the feedstock and are not separated from it. It is the impurities that give glass light shades of green and yellow. The last tone, for example, is associated with iron oxide.

Impurities have almost no effect on the quality parameters of silicate gel, since they are contained in the glue in fractions of a percent. Therefore, on packages with liquid glass, third-party compounds are either not listed at all or are indicated as “possible traces.” You know, they write something like this on sausages: “Possible traces of soy.”

No. 10. Waterproofing a well with liquid glass

Waterproofing work in this case is aimed at protecting the walls of the well from moisture, as well as treating the seams. It is very important that the concrete rings are very well fixed, otherwise no amount of waterproofing will save the structure from destruction. Additional fixation can be achieved using staples.

When the rings are mounted and they are secured, it is better to ensure that the seams are covered with linen or jute rope, pre-treated with liquid glass.

After this, you can begin processing the walls of the well. First, clean liquid glass is applied, and after it dries, a solution prepared on the basis of liquid glass and a cement-sand mixture is applied.

All the most important things about liquid glass

Liquid glass means a solution whose structure includes water and the minerals potassium or sodium. Due to its viscosity, it is excellent for waterproofing applications. Nowadays, the material has found active use in construction, this is due to a number of its positive qualities.

1.1

Features of the structure

By examining the composition of an alkaline solution, you can see tiny crystals. After applying them to the surface, they expand, filling all minor depressions and cracks. It is this property that creates the effect of water repellency and tightness. The main principle of action of this substance is its adhesive parameters. The reason for this is the ability of the molecules of an alkaline solution to penetrate into the constituent parts of a solid material and adhere to them.

In its constitution, liquid glass is similar to rubber in the same state. The surface with the solution applied to it becomes airtight and waterproof. When producing an alkaline material, quartz sand or soda is added to the silicates included in its structure, then crushed and roasted, and then crushed a second time to convert the mixture into a powdery mass.

Liquid glass has the following features:

water-repellent ability; preventing the formation of harmful microorganisms (antiseptic); eliminating electrification (antistatic); giving the material reliability (hardener); safety from the effects of all kinds of acids; fire safety.

1.2

Advantages and weaknesses

Liquid glass has a large number of advantages, the main ones are as follows:

1. The structure of the material helps to increase the level of adhesion, due to the ability to penetrate into various grooves and cracks, including minimal ones. This property allows you to easily cover planes of such categories as concrete and wood.2. Liquid glass creates a water-repellent film, thereby making the surface moisture-resistant.3. To carry out the work, a small amount of this building material is required. Consumption is significantly reduced by combining it with a cement composition to perform penetrating waterproofing.4. Compared to other materials for use for the same purposes, the alkaline composition has a reasonable price.5. Waterproofing provided with liquid glass can be used for up to five years. To slow down the process of self-destruction of such a material, it is necessary to apply a layer of paint with protective functions to it. This option can extend its service life.6. It is quite possible to carry out insulation measures in conditions with high levels of humidity. What cannot be done with other consumables with a similar purpose.

In addition to a number of significant advantages, it is worth highlighting some disadvantages:

1. Narrow scope of application, as a waterproofing only allowed for surfaces made of concrete or wood. Work related to providing protection against moisture penetration of brick surfaces is strictly prohibited due to the likelihood of destruction.2. The formation of a rather fragile film, which excludes the possibility of using by combining several types of waterproofing.3. Difficulties in application, requiring certain skills to perform the work well.

1.3

Scope of use

The use of liquid glass for waterproofing applies to many technological issues that arise during construction activities:

1. Protection of concrete from penetration of groundwater with the help of this material is carried out when working indoors and outdoors. After undergoing such treatment, concrete loses sensitivity to moisture and acquires the ability to operate even in underwater conditions.2. Waterproofing a pool using liquid glass is considered an excellent solution. The material allows you to achieve the desired effect at minimal cost. In this case, the use of a special film will be accompanied by significant difficulties, which cannot be said about glass.3. Waterproofing the basement with this compound prevents water from entering the room. This is especially noticeable in the spring when the groundwater level rapidly rises or the river floods heavily. The created protective layer will not allow the liquid to cross certain boundaries.4. To provide a residential building with comfortable conditions, its foundation is treated. As a result of this procedure, the foundation of the house will not be able to let moisture and liquid inside.5. In rare cases, work is carried out to waterproof walls using an alkaline solution. Despite the fact that practically no moisture seeps through these structural elements, such procedures are quite acceptable. For these purposes, building materials are purchased in much larger quantities.6. A fairly common solution is to waterproof a well using liquid glass. In this case, the walls are covered with material from the inside in two layers. The first layer is applied in its pure form, and the subsequent one will be applied as part of a mortar with cement; in this way, high results can be achieved.7. The ideal solution would be to waterproof the bathroom floor using an alkaline composition. The structure of the building material will allow it to penetrate even the smallest recesses of the base of the room.

Heat-resistant concrete on liquid glass

This section of our site discusses the processes occurring in cement stone on liquid glass when heated, as well as the main heat-resistant properties of hardened cement. Cement stone here is conventionally called a hardened solution on liquid glass with the addition of sodium silicofluoride and various types of finely ground mineral fillers. According to its properties, liquid glass (or soluble glass) is a very active substance that, especially when heated, interacts with the filler to form new substances.

Liquid glass contains a large amount of sodium oxide, which, being a strong flux, when introduced into the mixture, significantly reduces its fire resistance. The ability of soluble glass to react at high temperatures with both silica and various silicates opens up wide opportunities for the production of all kinds of new silicate materials with more or less high fire resistance and fire resistance. The addition of liquid glass to refractory materials reduces their fire resistance to a lesser extent than the introduction of other liquids. This led to the widespread use of liquid glass in the manufacture of refractory materials.

Since in refractory concrete of the type under consideration and in acid-resistant concrete the binder is liquid glass, it is appropriate to briefly highlight some of the properties of acid-resistant concrete. Liquid glass is used as a binder for acid-resistant concrete with a modulus (ratio of silica to sodium oxide) of 2.6-3.0 and density (specific gravity) 1.36-1.38.The lower the modulus of liquid glass, the higher the compressive strength of acid-resistant cement samples.

This phenomenon is explained by the fact that in cements based on liquid glass with a modulus not higher than 3, mainly crystalline rather than colloidal phases predominate. Moreover, the higher the modulus of liquid glass and the older the cement, the more pronounced its crystalline structure. Consequently, the modulus of liquid glass has a significant impact on the hardening processes and on the properties of acid-resistant concrete. In addition, the microstructure of hardened cement depends on the modulus of liquid glass. When heated, crystalline and colloidal substances behave differently. The hardening process of acid-resistant cements is explained by the interaction reaction between liquid glass and sodium fluoride, which proceeds according to the following scheme: NaaaSiFe + 6H20 + 2Na2SiO ↔: 6NaF + 3Si (OH),.

Quartz, sand and, in general, any rock with a high silica content are inert fillers that form a kind of skeleton. Hardening at normal temperatures of various cements on liquid glass without the addition of sodium fluoride proceeds extremely slowly, and the hardening process does not occur throughout the entire thickness of the cement stone, but only from the surface in contact with air. This forms a crust that protects the deeper layers from further hardening. The process of setting and hardening of cement occurs not due to a chemical reaction between the aggregate and sodium silicate, but due to the evaporation of water and, consequently, drying of the material. The hardening processes between sodium silicate and sodium fluoride are explained by the hydrolysis of Na2SiF6 and Na2Si03 followed by the interaction of hydrogen fluoride and free alkali with each other.

Na2SiF6 + 4H20 ↔ 2NaF + 4NaF + Si (OH)4; Na20 pSi02 + H20 ↔ 2NaOH + (p - 1)H20-Si02; NaOH + HF. =NaF + H20.

The hardening processes of acid-resistant mixtures are explained as follows: alkali silicate always contains a part of free alkali, which is in chemical equilibrium with silicic acid SiO2. Sodium silicofluoride reacts with NaOH following the following scheme: Na2SiF6 + 4NaOH = 6NaF + Si(OH)4. When NaOH transforms into the more stable neutral salt of sodium fluoride, silicic acid is released, which can form polysilicates by reacting with the remaining alkali silicate and accelerating the hardening process. In addition, the released silicic acid retains a certain amount of water, which also accelerates the hardening process.

With the introduction of a large amount of sodium fluoride silico, the strength of the cement stone decreases due to the complete destruction of the alkali silicate with the formation of the final products NaF and Si(OH)4, which have less cementing ability than the alkali multimodular silicate. The author considers crystalline quartz introduced into silicate cement not as a neutral filler, but as a component that interacts with liquid glass to form multimodular alkali silicates.

Free sodium hydroxide present in the sodium silicate solution increases the solubility of the silicic acid gel and protects against rapid precipitation of Si(OH)4. If free caustic sodium is removed from the solution, the silicic acid gel will precipitate faster and thereby accelerate the hardening process of the cement. Sodium silicofluoride, combining with NaOH, neutralizes it and prevents the reverse dissolution of the Si(OH)4 gel. Carbon dioxide in the air has the same meaning.

Liquid glass of the composition Na2Si205 9H20 used in acid-resistant cements interacts with sodium fluorosilicone according to the above schemes. There is also an interaction between Si02 and NaF with the formation of the complex compound 4.5Si02 NaF H20. Under the influence of sodium fluoride, colloidal processes occur in alkali-silicate mixtures, consisting in the coagulation of a sol of liquid glass silicic acid. The hardening of cements on liquid glass with the addition of sodium silicofluoride is explained not by coagulation, but by some features of sodium silicofluoride.

Part of Na2SiF6 enters into a chemical interaction with a solution of sodium silicate, forming sodium fluoride and silicic acid, the other part is part of the colloidal disperse system and forms a rubber-like mass. A small amount reacts with carbon dioxide in the air.

Hardening of cements on liquid glass throughout the entire thickness of the cement stone can only occur in the presence of sodium silicofluoride. In this case, a chemical interaction occurs between sodium silicate and sodium fluoride with the formation of NaF and Si(OH)4. Microscopic and radiographic studies of hardened liquid glass with the addition of sodium fluoride silicofluoride established the presence of sodium fluoride and silicic acid gel. Hardened cements on liquid glass with the addition of 12% Na2SiF6 do not have the endothermic effect characteristic of sodium silicofluoride at a temperature of 550-600°, caused by the decomposition of Na2SiF6 into NaF and SiF4. This indicates that during hardening of silicate cement, complete decomposition of sodium silicofluoride occurs due to hydrolysis and interaction of Na2SiF6 with NaOH.

The decomposition of sodium silicate by sodium fluoride occurs when the alkali has not yet completely reacted. In this regard, the amount of sodium silicofluoride required to ensure the setting and hardening processes can be reduced compared to the amount required to completely bind the alkali. For the reaction to proceed completely, it is necessary to introduce sodium silicofluoride in an amount of 41.2% by weight of sodium silicate. As a result of the reaction, silica appears in a gel-like state and the amount of colloidal silica detected by analysis exactly coincides with that calculated from the reaction.

How to waterproof a pool or well with liquid glass - step-by-step diagram

Step 1: Preparatory work

Preparing the mixture with your own hands is not at all difficult, but we must not forget about safety measures. Be sure to use protective gloves, and if liquid glass does get on the skin of your hands, you must immediately rinse it with running water. And to protect your clothes and shoes, you need to wear appropriate overalls.

Step 2: Improving concrete properties

Do you want to get a solid foundation or are you building a well or swimming pool?
In this case, you can add a little liquid glass to the cement-sand mixture. It should be remembered that waterproofing the foundation with liquid glass will worsen the strength of concrete. In this regard, the additive content should not exceed 5%! (MISSING) In addition, it is desirable to further strengthen the structure with reinforcement and the thickness of the sand cushion can be increased. We dilute liquid glass in water until a homogeneous mass is obtained. Then mix cement with sand and add a solution based on silicate glue. Mix everything well and pour into the formwork. This cement mixture hardens much faster than plain concrete. Moreover, it cannot be disturbed as soon as the hardening process has begun, so it is necessary to correctly calculate the volumes and act very quickly. Otherwise, material consumption will increase, and the savings will be dubious. You should also refrain from using a deep vibrator so as not to disrupt the crystal formation process.

Step 3: Processing seams and joints

This technology is also not complicated, and you can easily do the work yourself. Liquid glass is mixed with water in a ratio of 1:10 or 1:15. Next, pour the solution into the cement and mix the mixture until a homogeneous mass is obtained. Using a spatula, fill the embroidered and cleaned seams with a paste-like composition. The amount of glue in the solution should also not exceed 5%!

Step 4: Coating waterproofing method

And this technology is used in cases where the use of solutions containing bitumen is undesirable. The surface is thoroughly cleaned and brushed to open the pores as much as possible. Then, using a brush, a thin layer of liquid glass is applied. Once the first layer has dried, you can treat the surface again. As you can see, the process is absolutely not complicated and can be done with your own hands. However, it must be clearly understood that sodium silicate itself does not provide adequate protection; it only improves the characteristics of the material by interacting with it and filling its pores. This method is popular if waterproofing the floor with liquid glass is necessary. If we talk about the treatment of wells and pools, then it is better to give preference to the first method, although sometimes the use of coating technology is also welcome.

Proportions and application of liquid glass

Standard glass proportions are 65-76% silicon dioxide. The rest is sodium, potassium or lithium oxide. If we are talking about ammonium composition, the proportion of silica increases to 85%.

Soda glass contains approximately 7% more silicon dioxide by weight of the total mass. By the way, this mass is not only used to impregnate already cast concrete. Glass is also added to it at the mixing stage. This not only eliminates the porosity of the material, but also adds heat-resistant and acid-resistant parameters.

The liquid is mixed both with standard concrete and with its varieties such as wood concrete. This is the name of chips rolled in cement and held together by it. Artificial stone protects wood material from the destructive effects of moisture.

Chips, in turn, lighten the blocks and preserve their environmental friendliness. The addition of liquid glass to concrete eliminates even the minimal risk of moisture penetration into the wood filler.

The average consumption of liquid glass when coating surfaces is 200-400 grams per square meter. If you mix the gel into solutions, the consumption reaches 150 grams for every kilogram of the mixture. The latter can be not only concrete, but also plaster. Glass makes the latter resistant to fungi and mold.

Liquid glass in construction is just one of many areas of application of silicate gel. For example, they impregnate textiles. The tissues become hard, like plastic. There are also such wallpapers. Some wall canvases are made entirely of glass, but not gel, but its thread-like form. Silicate fibers are woven like yarn in ordinary fabric.

Potassium glass is more heat resistant than sodium glass. Therefore, gels with potassium oxide are used to repair high-temperature furnaces. In these they create ceramics and burn bricks. Additionally, potassium glue is used in the production of welding electrodes.

If polishing with liquid glass , potassium gels are also used. This was mentioned in passing. Let us add that liquid glass can produce a mirror surface not only on metal, be it pristine or painted.

Liquid glass is also used for polishing cars

You can polish silicate glue to a shine on wood and even concrete. This gives the gray and nondescript material a previously unseen shine. It remains to be seen how much the transformation will cost.

Preparation of mortars with liquid glass

Manufacturing proportions

To obtain the expected effect from the use of silicate compounds, they must be properly prepared for work. For example, if you plan to cover the surface of a concrete floor with liquid glass, then it must be diluted with water in a ratio of 1:2. That is, 1 kg of glass will require two liters of water. The consumption of such a solution will be 250÷300 g/m².

Liquid glass is used for waterproofing concrete floors and plastered surfaces, on which the coating has lost its strength over the period of operation and has unevenness. The silicate solution will bind the structure of the material, give it strength, make the surface smoother, and also create antiseptic protection for it.

Adding liquid glass to the concrete solution gives the structure waterproofing qualities. In addition, this additive significantly accelerates the hardening process of concrete.

If liquid glass is added to concrete mortar, the proportions may vary depending on the area of ​​its application. The content of the silicate composition can have different effects on the physical characteristics and hardening period of the solution. For concrete mortar reinforced with silicate additive, it is necessary to use cement grades M300 and M400.

If liquid glass is added to a cement-sand mortar in an amount of 2%!o(MISSING)t of the total mass, then the life of the solution will be 40 minutes. After which the mixture will begin to quickly harden. And complete drying will take 24 hours. If silicate glue makes up 10% of the total volume of cement, then hardening will begin much faster. Such proportions of components will ensure that the mixture begins to set within 5 minutes. Well, complete drying will be achieved in 4 hours. If you make a 1:1 solution, that is, use 1 kg of glue for 1 kg of cement, then hardening will occur within one or two minutes after mixing it. This approach is often used to quickly eliminate leaks caused by cracks.

Waterproofing the floor with liquid glass.

To waterproof the floors of bathrooms, basements, inspection pits, garages, as well as swimming pools, a solution of cement and liquid glass, made up in a ratio of 10:1, is used. When making a heat-resistant mixture for laying a furnace, the solution should consist of 1 part cement, 3 parts sand and 0.2 parts liquid glass. As a result of using this proportion, a dough-like plastic mixture should be obtained, which is convenient to work with when laying bricks. If it is necessary to prepare a solution for waterproofing a well, then take cement, sand and liquid glass in a ratio of 1:1:1. The mixture must be brought to the consistency of liquid sour cream with water. Refractory solutions consist of the same components, but taken in a ratio of 4:1.5:1.5. To fill voids and cracks in a concrete base or load-bearing structures, the solution is prepared from 3 parts cement, 1 part sand and 1 part liquid glass. To strengthen facade surfaces, a waterproof plaster mixture is made, consisting of 0.5 parts silicate mass, 1 part cement and 2.5 parts sand.

Procedure for mixing the solution

It is not enough to know the proportions of the solution - you need to be able to make it correctly. To make the material homogeneous and plastic, you should follow some recommendations:

First of all, you should choose the proportions for making the solution, depending on the application. To work on mixing and applying a solution containing liquid glass, it is necessary to prepare special clothing. With the expectation that you wouldn’t mind throwing it away later. Washing silicate composition from fabric is a completely futile task. Next, you need to fill a suitable container with water. Its quantity depends on the volume of cement and sand that will be used for the solution. The next step is to pour liquid glass into the water and mix thoroughly until completely dissolved. A dry mixture consisting of sand and cement, taken in the required proportions, is mixed separately. After this, the cement-sand mixture is gradually poured into the aqueous silicate solution and mixed until smooth. It is better to carry out this process with a construction mixer or an electric drill, installing a special attachment on it. If the solution turns out to be too thick, you can carefully add a little water into it. The liquid mixture can be thickened by adding a little cement to it.

When making solutions containing liquid glass, we must not forget that the “pot life time,” that is, before its avalanche-like setting begins, is significantly reduced. Therefore, it is recommended to make the mixture in small portions so that it can be used in a short time. Naturally, they take into account their capabilities, the availability of assistants, accumulated experience, etc.

How to prepare a solution with liquid glass?

In construction, as well as in interior renovations, mixtures based on cement and liquid glass are widely used. At the same time, despite the special conditions of preparation and application, the antiseptic, hydrophobic, acid-resistant and fire-retardant properties of the structures obtained in this way prevail over the difficulties and disadvantages.

To create a waterproof layer, use a solution consisting of liquid glass and cement taken in a ratio of 1:10.

If the cooking instructions indicate the proportions of the components “by weight”, you should use the following values:

• Liquid glass: 1.5 kg/l:
• Part cement mixed with 4 parts sand: 2.5-2.7 kg/l;

The resulting mixture is used for the construction of self-leveling floors and improving the waterproofing qualities of walls of buildings and structures.

Waterproof (hydrophobic) plaster is used to protect the base material of the walls of buildings and structures from the harmful effects of water and high air humidity.

The use of a hydrophobic protective layer is especially important in the northern regions of Russia - regular freezing and thawing of moisture inside the walls usually leads to the appearance of cracks and subsequent destruction of the structure.

To prepare hydrophobic plaster yourself, the following proportions of liquid glass, cement and sifted sand are recommended: 1:2:5.

In home construction and renovation, sometimes it becomes necessary to cover a concrete screed with soil. For these purposes, prepare a solution of liquid glass and cement, mixed in a 1:1 ratio.

A solution made from liquid glass and cement can be used to fill cracks, voids and crevices. The material is prepared from liquid glass, Portland cement and sifted sand mixed in proportions: 1: 1: 3.

The solution prepared in this way has a thick consistency, due to which it adheres well to surface defects, and the high content of liquid glass contributes to its rapid “setting” and hardening.

The process of making a concrete mixture with liquid glass is not complicated and can be done even at home. However, in order to prepare a high-quality solution, certain requirements must be met. If this is not done, cracks may form in the concrete.

Typically glass is added to a dry mix rather than to a liquid concrete solution. Those. You must first mix the dry ingredients, and then pour glass diluted with water into them. Although there are exceptions to this rule when glass is added to a liquid solution.

It is very important to maintain the correct ratio of all components of the mixture. When adding liquid glass to concrete, the proportions of all components must be maintained in accordance with the requirements of the instructions for a specific composition. If we talk about the maximum amount of liquid glass in concrete, then it can reach 25% of the total mass of the mixture. When making primers, silicate glue and cement mortar are taken in a 1:1 ratio.

The glue speeds up the hardening of the mixture. This must be taken into account when working. You need to prepare the concrete in small portions in order to have time to work it before it hardens, or add a little water.

There is no shortage of advice on preparing mixtures with liquid glass. A large number of all kinds of recipes from amateur craftsmen are offered, and everyone decides for themselves whether to follow them or not. It is only necessary to note that this is a responsible matter, and it must be approached very seriously. Here are several proven recipes for preparing building mixtures with liquid glass.

Primer. Using clean glass as a primer is not always possible, so a mixture containing cement, liquid glass and water is prepared. For 1 kg of cement, 1 kg of glass is taken. Cement is mixed with water, liquid glass is added to the solution, and the whole thing is thoroughly mixed. When the primer hardens, you can add a little clean water to thin it.

Waterproofing composition for wells. Glass and well-sifted building sand are mixed well in a 1:1 ratio. The resulting solution can be coated with the walls of wells to waterproof them.

Mixture for waterproofing underground concrete premises. Waterproofing concrete with liquid glass is a widely used operation. 1 liter of silicate glue is added to 10 liters of concrete mortar. This composition provides reliable waterproofing of the walls and floors of basements, wells or other concrete structures located in damp soil.

Fireproof concrete mortar. The recipe for its preparation is simple. An ordinary cement-sand mortar is prepared, to which a little liquid glass is added at the end. Since this mixture dries faster than usual, it is recommended to prepare it in small portions.

Antiseptic for wood. Liquid glass is mixed with water in equal proportions. The protective film on material coated with this composition is slippery and cannot be painted. Therefore, it is not recommended for use on concrete walls.

Impregnation for various materials. For 1 liter of water take 0.4 kg of glass. Subsequent layers should be applied after the previous ones have completely dried.

We suggest you familiarize yourself with How to remove double-sided tape from glass and traces from it

In general, when using liquid glass as an impregnation or coating in cases where there is no specific preparation recipe, you can use the general rule - the glue is diluted with water in a ratio of 1:2.

To work with glass, you will need the appropriate tools. You must have a container for preparing the mixture and gloves. For stirring and application, use a brush, brush, or roller. If you plan to apply by spraying, you will need a spray gun.

When using pure glass or its mixture with concrete, the solution must be mixed well using a brush or broom.

The surface to be treated is thoroughly cleaned of organic and inorganic contaminants - dirt, dust, fats, oils, mold, etc. The concrete surface is degreased and, if necessary, leveled using putty. Glass can be applied with a brush, roller or spray gun. In this case, the glue is able to penetrate into the depth of the material up to 2 mm. To form a more reliable protective film, the composition must be applied in several layers.

Liquid glass does not contain harmful substances, but if it comes into contact with a naked body, the area must be washed with water. After finishing work with liquid glue or a composition containing it, you must completely wash off the remaining mixture from your hands and tools.

The properties of an aqueous-alkaline solution of potassium silicate make this material universal in use

Liquid potassium glass is the commercial name for an aqueous-alkaline solution of potassium or sodium silicate. The material, when applied in a thin layer and partially dries, forms a gelatinous gel-like coating. When completely dry, the substance forms a transparent hydrophobic sodium coating, which crumbles or becomes chipped under mechanical stress.

If the instructions for use are followed, potassium glass makes concrete waterproof

Silicate glue dissolves well in water, forming solutions with varying degrees of viscosity. A solution with a low degree of viscosity has high absorbency. Such means are widely used in construction.

• Before applying the product, the surface to be treated is thoroughly cleaned of contaminants that may reduce absorbency;
• Surfaces treated with silicate solution must dry for at least 24 hours;
• When applying the product in several layers, we take a mandatory break to dry each previous layer;
• Even after drying, the silicate crust crumbles easily, so you should not drag heavy furniture or heavy metal objects with sharp edges across the prepared floor;
• The product is applied like thick paint - with a brush or roller. In some cases, a plaster spatula can be used to form a protective coating.

Why choose liquid glass

Among other things, liquid glass has excellent adhesion to most surfaces. The material has an antiseptic effect and exhibits abrasion resistance during operation. This composition is characterized by anti-corrosion characteristics and even wind resistance.

Waterproofing with liquid glass is most common when using a composition as an ingredient. In its pure form, the material is used less often. During the production process, a mixture of quartz sand is fired with soda and crushed, this makes it possible to obtain a product that is then dissolved in water.

Liquid glass application.

Liquid glass is a unique material that has many properties and is used in various fields. Liquid glass is the most widely used in construction. Let's figure out what can be done with such a material as liquid glass.

The use of liquid glass for waterproofing is very common. It can be used to impregnate both walls and ceilings. In addition, we know that the foundations of buildings are often exposed to atmospheric influences: wastewater, temperature differences, and high humidity can greatly damage the foundation and base of the building. The use of liquid glass in the construction and finishing of foundations and plinths will significantly increase resistance to atmospheric influences.

Let's now imagine that you need to build a swimming pool in your dacha. If you simply dig a hole, line it and plaster it, the water will quickly find its way and the pool will leak: waterproofing is needed. Therefore, in this case, liquid glass is also useful; it was and continues to be used quite often in the construction of swimming pools. The same can be said about wells: waterproofing using liquid glass will also not hurt there.

Our next point is the use of liquid glass as an antiseptic. Quite often we can observe mold and mildew on the walls of residential and non-residential premises. And it doesn’t matter what these walls are made of or how they are decorated, if you don’t take care of antiseptic treatment, the fungus will manifest itself somewhere. Liquid glass is a very good antiseptic.

Liquid glass has good adhesion, that is, it sticks well to the surface, which is why it is used for gluing and bonding various kinds of materials. It can be used to glue cardboard, porcelain, glass, etc.

In order to increase the density and fire resistance of products made from paper, wood or any fabric, they are impregnated with the same liquid glass.

Preparing construction mixtures

Let's approach the issue from a practical point of view and consider what useful things can be done using liquid glass.

Preparation of liquid glass primer. Naturally, no one primes with pure liquid glass; it needs to be diluted.

In order to prepare the primer, in addition to liquid glass, you will also need cement and clean water. For 10 kg of cement you will need approximately the same mass of liquid glass. First, the cement is mixed with water; this can be done using a drill with an attachment (mixer). After which the mixture of cement and water is added to the liquid glass and also stirred.

If the resulting primer hardens too quickly and does not work properly, you need to add a little water and stir.

Waterproofing solution for wells. Before preparing the solution, the sand must be thoroughly sifted. Mix one part sand, one part cement and one part liquid glass.

First, coat the walls of the well with liquid glass, then go over it again with a waterproofing solution.

Production of fireproof mortar. Can be used for laying various types of fireplaces and stoves. There is nothing complicated here: first, prepare a regular cement-sand mortar (1 part cement: 3 parts sand), after which a little liquid glass (15-20% by weight of cement) is added to the solution.

Such a solution should not be diluted in too large portions because it “cools” quickly.

If you want to protect wood from fungus or mold, then you can prepare an antiseptic from liquid glass. Liquid glass is diluted with water 1:1.

It is better not to smear walls made of concrete or plastered with cement-sand mortar with this product. They are covered with a kind of protective film, which is very slippery and further finishing in the form of putty and painting becomes almost impossible.

Preparation of impregnation for the surface of materials. It is necessary to prepare a mixture of water and liquid glass. To do this, you will need to dissolve approximately 400 g in one liter of water. liquid glass. The surface is treated with a brush a couple of times, and there is no need to start re-impregnation until the previous layer has completely dried.

Of course, today there are a lot of materials on the shelves of construction stores: these are primers, waterproofing materials, adhesives, and ready-made fireproof solutions. Therefore, liquid glass in its pure form is an amateur material; sometimes it is better to use a ready-made solution rather than mix something up, observing the proportions. Why reinvent the wheel, right? This liquid glass used to be used in its pure form by everyone and everywhere, but now it is used as a separate ingredient of one or another building mixture.

All this does not mean that liquid glass in its pure form has been completely written off. Some builders continue to actively use it because they have long established their proportions and prepare their own building mixtures, which have been proven over the years.

Advantages and disadvantages of the composition

Liquid glass offered by modern brands has many advantages, due to which the product remains a leader in demand. The solution is an easy-to-use “liquid” substance. The product quickly gets into small defects on the surface, filling them and creating a smooth surface. The composition can be used on surfaces made of various materials (concrete and wood bases).

And it is also worth noting many advantages.

The material has excellent adhesion. Economical consumption allows you to carry out work with a minimum of costs, especially when adding the composition to the cement mortar. In this case, the product works as a penetrating waterproofing.

Affordable price played an important role in the distribution of the product. The product price is more favorable compared to other waterproofing materials. A long service life indicates practicality and reliability. This indicator is 5 years. To extend the time of use, liquid glass is coated with a layer of enamel, which plays the role of additional protection. The product can be used in rooms with high humidity, which is impossible with other insulators (bathroom, swimming pool, basement, etc.). A harmless, environmentally friendly and safe product, due to which the work can be carried out from the inside. Considering the popularity of the product, finding the appropriate composition on store shelves will not be difficult.

All of the above characteristics are possessed only by original products, which have passed control at all stages of production and have been tested before being sent to stores.

Among the shortcomings, some nuances can be noted.

Brick surfaces cannot be treated with the solution, otherwise destruction is possible. Working with the product is not easy. Experts note that the application process is complex, and to perform it you need to have certain skills. After application, the composition quickly sets, forming a film. Therefore, the work must be done as quickly as possible and at the same time carefully. The cured consumable composition is quite fragile, and therefore it must be combined with other types of waterproofing.

Surface preparation

Before using sodium silicate for waterproofing, the surface must be cleaned of dirt, paint, rust, plaster, dusted (you can use a household or industrial vacuum cleaner) and degreased, leveled if necessary, and nails and screws removed.

For coating waterproofing, which is used for floors, swimming pools, wells, the surface is first cleaned with a brush to open the pores in the concrete. The walls of wells and swimming pools are washed so that all defects become more noticeable. After this, the surfaces should dry. To prevent fungus from developing, they are treated with an antiseptic. Wooden surfaces, for example, the floor of a bathhouse or sauna, are treated with a fire retardant to give the wood fire-resistant properties.
