Expanded clay concrete wall blocks, despite the fact that they are quite light, they are still durable and their strength depends on the density of expanded clay concrete from which the blocks are made. The density of expanded clay concrete is measured in kg/m3 and starts from 350 kg/m3 and reaches 1800 kg/m3. Such a relatively low density is easily explained by the expanded clay included in the solution. Despite all this, expanded clay concrete comes in different categories and different qualities. For example, large-porous expanded clay concrete is made without the use of sand.

Density of expanded clay concrete kg m3

I think it’s not difficult to guess that the density of expanded clay concrete primarily depends on expanded clay, or rather its weight, or more specifically, on its density, which varies with the degree of porosity. Secondly, it depends on the proportion of expanded clay and concrete in expanded clay concrete. Since expanded clay has the lowest density among all the components included in expanded clay concrete, this means that the more expanded clay there is, the lower the density of expanded clay concrete will be.

Here you need to decide what the expanded clay concrete will be used for; if for the construction of walls made of expanded clay concrete or various floors, then only dense concrete must be used, with a lower content of expanded clay, which has strength many times higher.

Expanded clay concrete comes in 3 types:

Structural expanded clay concrete
Thermal insulating expanded clay concrete
Structural thermal insulation expanded clay concrete

Types and classification of expanded clay concrete

Depending on its type, purpose, density and other properties and characteristics, expanded clay concrete has its own classification.

By product type

Expanded clay concrete can be produced in the form of blocks, panels and slabs.

The blocks have the form of building elements of the correct shape and with standard parameters. They consist of expanded clay, sand, water and cement. The role of the binding component is played by Portland cement of a grade not lower than M400. To increase water-repellent properties, hydrophobic cement can be added to blocks
Expanded clay concrete panels Their dimensions can vary within the following range: length from 30 to 720 cm, height from 30 to 810 cm. They are usually used for mounting the external part of the wall and creating partitions indoors. They can also be used to fill the frame of reinforced concrete structures.
slabs have received good reviews; they are a monolithic structure reinforced with a steel frame. They are highly durable and therefore are actively used in the construction of buildings with high loads.

Next we will tell you about structural thermal insulation blocks,

By granule density

Based on the density of the concrete used, the building material is divided into three types:

Dense expanded clay concrete . It has a high density (up to 2000 kg/m3). The main area of use is the creation of foundations and various load-bearing structures, which must have high strength.
Sandless or large-porous expanded clay concrete . It consists of fractions of expanded clay gravel and crushed stone up to 2 cm in diameter, Portland cement M300-M400 and water. Due to the absence of sand in the composition, the density of the finished material decreases by 600 kg/m3 and is about 1800 kg/m3. It is actively used for the construction of monolithic structures and wall blocks.
Painted expanded clay concrete Depending on the scope of application, it is divided into:
Structurally – heat-insulating (density about 800-1200 kg/m3). Designed for the production of large blocks and single-layer panels.
Structural (density 1500-1800 kg/m3). Used for the construction of load-bearing structures, various building structures and in shipbuilding. High strength and reliability have led to its widespread use.

The strength of the material depends on the strength of the expanded clay and cement used.

By application

Depending on the scope of application for which expanded clay concrete is made, it is divided into:

wall blocks have received positive reviews and are used for the construction of walls in low-rise construction.
Foundation blocks intended for the construction of the foundation of any building and structure. Due to bearing large loads, they are more durable than wall ones.
Partition blocks are used to organize internal partitions and ceilings.
Ventilation blocks made of expanded clay concrete deserve positive reviews; they are a porous material that prevents the appearance of fungus and mold.

Next, we will consider the comparative characteristics of monolithic expanded clay concrete, the thickness of the walls made from it, and we will also tell you how to make a monolith from expanded clay concrete with your own hands.

By solidity

Monolithic expanded clay concrete is a fairly common type. The material is formed by combining expanded clay with lime, cement or gypsum.

The result is an environmentally friendly material that is not inferior in its technical characteristics to ceramic bricks and makes low-rise construction from monolithic expanded clay concrete simply ideal.

To create monolithic expanded clay concrete, it is necessary to observe the proportions and all the technology for its production, as well as use the necessary components.

To begin with, 1 part of cement is placed in a concrete mixer, then 2 parts of sand.
These two components are thoroughly mixed together, after which 1 part of water and 3 parts of expanded clay are added, then they are mixed again. The mass should be quite moist. Water is added until the dissolved cement covers all the expanded clay granules.
The resulting mixture is poured into the formwork.

In this case, the finished mixture should be isolated from slabs, bricks and other materials. Otherwise, monolithic expanded clay concrete will give up its moisture to another material. For these purposes, polyethylene, mastic or special emulsions are used.

The monolithic crystalline hydrate sets on the second day, at which time the finishing layers can be made. Monolithic expanded clay concrete itself will fully gain its strength within a month. To regulate its microclimate, the structure is covered with a film or its surface is regularly moistened.

You will learn which brand of expanded clay concrete is better in terms of strength, reliability and other parameters in the next section.
