GOST 26633-91 “Heavy and fine-grained concrete. Technical specifications"

GOST 26633 2012 heavy and fine-grained concrete. Application area

• Making curb stones.
• Pouring foundations for high-rise buildings.
• Pillow for road surfaces.
• Manufacturing of reinforced concrete products.
• Hydraulic structures.

The main feature of heavy concrete GOST 26633 2012 is its high density, which is achieved by mixing a large amount of high-quality cement with fine and coarse filler in an optimal ratio.

Heavy concrete GOST 74732010 technical characteristics

According to GOST requirements, this type of concrete must meet the following technical indicators:

• Medium density.
• Workability.
• Temperature.
• Delamination.
• Porosity.
• Volume of entrained air.
• Stability of properties over time.

Areas of functional application of the material

• Production of load-bearing walls of structures.
• Manufacturing of reinforced concrete products.
• Construction of monolithic structures.

GOST 26633 91 heavy and fine-grained concrete

This type of concrete is suitable for individual construction. Durable, but relatively thin material due to the inclusion of small filler fractions. It does not contain large crushed stone and gravel. Suitable mixture for finishing work.

Specifications

• Water resistance - W6-W12.
• Frost resistance - F500.
• Shrinkage – 0.15 mm per 1 m.
• Tensile strength – Bt10-Bt40.

It is these requirements that heavy concrete GOST 26633 91 must meet. Carefully study the parameters when choosing materials for construction.

produces strictly in accordance with GOST and independently sells concrete mixtures since 2002. We work with large enterprises and private buyers. Thanks to our own production and direct cooperation with the client, we are able to offer products at a low price. This does not in any way affect the highest quality of our mixtures.

Concrete according to GOST

Concrete is the most common building material. There are many types of concrete, which are used depending on specific conditions and requirements. When preparing a concrete mixture, there are rules for selecting the composition of concrete, which are regulated by the requirements of GOST 27006-86. The selection of workers is carried out in several stages.

1. Selecting a material for concrete with certain characteristics.

2. Calculation of the starting composition and proportion of concrete.

3. Additional calculation of the composition to obtain concrete with certain characteristics.

4. Preparation of concrete, sampling, testing of samples.

5. Determination of the nominal composition of the concrete mixture.

Concrete components according to GOST

Any concrete is a mixture of water, cement and filler. The main requirements for the components are that they should not contain foreign inclusions or impurities. Only fresh water should be used.

To prepare the mixture, there is a special concrete table, from which you can familiarize yourself with the composition of certain grades of concrete.

Heavy concrete GOST 26633 2012

Heavy concrete GOST 26633 2012 is used for the construction of special-purpose facilities: nuclear power plants, bunkers, bridges, hydraulic structures. This is a type of especially strong, dense concrete that can withstand heavy loads and does not collapse under the influence of the environment.

Strength of concrete GOST

The standards have been developed over decades. Currently, they are being supplemented and edited, albeit slightly. Strength refers to the load that a mixture can withstand without breaking. There is a certain GOST for the strength of concrete, where the strength is determined in laboratories.

Load is measured in MPa. There are two ways to indicate strength: grade and compressive class of concrete. The stamp encodes the pressure in kilograms per square centimeter of plane. That is, if the M-200 brand is indicated, then this means the following.

The structure does not collapse if it is acted upon with a force of 200 kg/sq.cm. Other brands - accordingly. By destruction we mean a violation of integrity. This does not always mean an array bursting in two. Any crack, missing parts, chips and other visual damage indicate destruction .

The concrete class encrypts the load already in Megapascals. This is a requirement of international standards. B25 concrete means that the maximum non-destructive load is 25 MPa.
