Rating of the best Russian manufacturers of aerated concrete blocks for 2025

Aerated concrete blocks have long become a fairly popular material that allows you to quickly, efficiently and at no extra cost to build small buildings. Among other things, this building material can be easily processed, and it is very simple to repair structures from it.

Aerated concrete blocks: general information

They are a mixture of sand, lime and cement and, in fact, are one of the modifications of cellular concrete. Material of artificial nature with the presence of porous inclusions, which are 85% filled with gas or air. It is due to these characteristics that the blocks are light in weight and have a low degree of thermal conductivity.

During their production, gas is formed as a result of the chemical reaction of the gas-forming agent, which is aluminum powder or a paste consisting of a binder, sand and water. Also, pores in aerated concrete building modules are formed when foam is mixed with a special foam solution that has a foaming agent in its structure. The type of material under consideration is divided into varieties that are formed when using a different binder. Products can be made on the basis of Portland cement, slag concrete, a mixture of lime and cement, gas-slag concrete and foam-slag concrete. At the same time, it is possible to use gas silicate or foam silicate as the basis.

According to the final purpose of the application, the modules can be intended for thermal insulation or be purely structural (a thermal insulation and structural option is also possible). Their production itself can be carried out according to the autoclave and non-autoclave method. The latter method involves manual production, i.e. in the production part, process automation is not used at all, and everything is done exclusively by hand - the mixture is kneaded with shovels or a special mechanism driven by human muscle power. It is worth using products made by this method only if they are produced independently, but in extreme cases - at your own peril and risk.

Specifications

Aerated concrete is an artificial stone with a porous cement structure. The composition includes quicklime diluted with aluminum paste with sand, cement and water. This is how a building module is obtained, in which the internal pores are evenly filled with air. It is thanks to these pores that aerated concrete has a light weight, excellent thermal insulation and is very easy to process. Calcium silicates created during the production process are absolutely harmless to humans. There is no crushed stone in the structure, the proportion of cement is from 50 to 60%, and a homogeneous device is given to the material with a mediocre foamed lime.

The material itself was invented in Sweden at the end of the 19th century, and it was supposed to be used exclusively for the construction of complex and multilayer walls, in order to reduce their heat transfer.

Later, in the course of improving the technology, the possibility of building low-rise prefabricated structures from such products (both residential and industrial) was established.

Foam concrete and aerated concrete - the main differences

In modern construction of prefabricated structures, porous blocks are often used, where foam concrete, aerated concrete and aerated concrete are the leaders. They differ from each other in the way they are produced. Aerated concretes, in most cases, use the autoclave manufacturing procedure, are characterized by high strength and density, and have uniform thermal conductivity. It is the autoclave method that gives them rigidity and strength. He is also responsible for the fact that aerated concrete, unlike other models, shrinks by only 0.3 millimeters against 2-3 millimeters for other types. Factory aerated concrete is devoid of a pronounced smell of lime and does not have increased properties of corrosive activity. More specifically, aerated concrete differs from foam concrete in the following properties:

• It is cut from monolithic modules and has clear geometric shapes, and thanks to the exact dimensions, it is possible to simplify laying work and optimize the consumption of plaster;
• Aerated concrete fits perfectly on a special adhesive mixture, which reduces the formation of "cold bridges";
• Small aerated concrete pores “grab” the plaster easier and faster;
• Aerated concrete products are of an industrial nature, which excludes underweights/overweights for each individual module. Foam concrete can be made in a handicraft way, which is why products made from it are deprived of precise shapes and weight.

Advantages and disadvantages of aerated concrete construction

Initially, the type of building material in question was to be used for laying concrete frames in industrial buildings and was not at all intended for use in civil engineering.When erecting residential buildings for these blocks, it is necessary to take into account their positive qualities:

• They are much lighter than brick and concrete, respectively, there is no need for a massive foundation;
• Have a high degree of fire safety;
• Completely environmentally friendly and do not harm human health;
• They are not subject to decay and cannot be damaged by pests, which means that there is no need for treatment with special chemical compounds.

Some of the "cons" of this material include:

• May shrink as much as 0.5 millimeters per meter in the first month after installation, which may be caused by high humidity conditions. If you maintain the required level, then shrinkage immediately stops. This situation can also be influenced by the geographic region of construction, the thickness and density of block modules, and the time of year in which the masonry was carried out.
• Due to its porous structure, aerated concrete perfectly absorbs moisture, so it will need additional protection both from the outside and from the inside. During construction, the unfinished structure is required to be covered during the shutdown with a waterproofing coating that is protected from snow and rain.
• Finished walls are subject to mandatory cladding. The best result will be a combination with ceramic blocks or standard bricks, but the cladding should not take place immediately after the walls are erected - they must dry properly so that moisture leaves the structure.
• The white-gray surface does not look very aesthetically pleasing, so it would be a smart decision to finish it with facade coatings.
• It is preferable to build a structure from freshly made modules, and not from those that have been stored for a long time.When idle, the density of aerated concrete will decrease.

Types of aerated concrete blocks

The marking of this type of building components looks like the Latin letter "D" with a numerical value that indicates the density of the material. For example, D-500 speaks of a block density of 500 kilograms per square meter. Depending on the density, there are three types of block products:

1. Thermal insulation;
2. Structural and heat-insulating;
3. Structural.

When marking the described products, their purpose must be clearly indicated, no substitution of characteristics is allowed. Unscrupulous labeling will increase the risk of using the building material for other purposes, which clearly threatens to worsen the technical parameters of the building under construction and easily lead to the collapse of the entire structure.

Thermal insulation

These modules include the marking D 300-400. With such a low density, the material gives off heat weakly, but its smaller number of pores indicates low strength. It is customary to build load-bearing walls from such products, the operation of which will not be designed for excessive load (with the exception of its own weight). An excellent example here would be buildings with a spatial framework based on reinforced concrete columns or panels. It is enough to fill the areas of the outer walls with products, leaving door and window openings in them. For each storey wall, support must be made on the ceiling, and the maximum height should not exceed one storey. Such a construction is not capable of subjecting the block structure to a heavy load.

Structural and heat-insulating

This type of product is marked D 500-900 and is considered universal. The blocks are able to withstand significant loads, however, have low thermal conductivity.These modules can be used for the construction of two or three-story structures, even if their internal partitions and ceilings are made of reinforced concrete. For regions with a temperate climate, insulation is not required. It is preferable to use this block product for the construction of private small houses.

Structural

For these blocks, the density is equal to or greater than 1000 kilograms per square meter, i.e. marking starts from D1000. Such aerated concrete can be used to construct the walls of buildings with several floors. Due to the increased density of the material, any laying element from it (especially during construction in areas with a cold climate) needs additional insulation. Also, such modules can be reinforced and used as lintels, slabs and beams for prefabricated floors. Nevertheless, despite the high density, this type is not allowed to be used as a foundation. Even with increased density indicators, the material will absorb a sufficient amount of excess moisture, which will certainly lead to its subsequent destruction. Based on the same reason, D1000 needs to make a horizontal waterproofing between the walls and the foundation.

Difficulties of choice

Before starting the construction process, it is necessary to decide what type of aerated concrete products should be used for partitions and walls. The modern Russian assortment of these products is so diverse that it will be very difficult to make the only right choice. It is always worth remembering that the use of modules with the correct geometry will save plaster and adhesive composition. The same property will reduce the cost of heating the future premises and its thermal insulation.In any case, first of all, you need to pay attention to the brand, frost resistance, overall density, size and shape.

purpose

Most often, partition and wall products with a U-shaped profile come across on the Russian market. The material for the outer walls should be thicker so that it is possible to lay all the modules in just one row. This type of construction will increase its pace, while reducing the risk of the formation of "cold bridges". For partitions, products with a small thickness are suitable, which will allow more efficient use of internal usable areas. However, such blocks should be subject to increased requirements in terms of soundproofing characteristics, which is important for partitions. Also, the U-profile will be an excellent solution for the design of door and window lintels. Their cutout can be adjusted to the required length of reinforcement, which will provide a greater degree of load-bearing capacity.

Manufacturing technology

Autoclave production uses the same raw materials as non-autoclave production. The main difference between the products will be the heat treatment of the product. Some manufacturers in the Russian Federation prefer to carry out drying through a natural way, but this will necessarily affect the stability of density and dimensions, while at the same time negatively affecting the thermal parameters, which is not allowed by autoclave production. The latest technology is inherent in the implementation of high-pressure steam heat treatment - this increases the density of the building material, ensures normal geometry and the correct dimensions.Still, autoclave automatic production using high technologies is typical for Russia, which indicates a sufficient level of quality.

Marking

On this subject, it is always worth keeping in mind that the grade will depend on the density. The higher the brand, the stronger and heavier the block will be. A marking of 500 units means the possibility of building load-bearing or external walls, 600-700 units - suitable for the construction of load-bearing structures in houses with a number of storeys of 3 or more floors. 300 units is the best choice for internal wall partitions, and the 200 unit option can only be considered as additional insulation.

Shapes and dimensions

Russian manufacturers have already launched the production of dozens of standard sizes of aerated concrete blocks. Their selection will depend on the region of construction and its climate. The thickness is selected on the basis of thermal engineering features, and the length and height - depending on their need for each specific design. For external walls, the largest possible products are purchased, which allows you to speed up the workflow by using fewer blocks, while simultaneously reducing the consumption of adhesive. The Russians prefer a more rectangular shape with a tongue-and-groove lock. Of products with a rectangular shape, it is easiest to build partitions, and the "comb-groove" system will make the inter-unit connection more durable.

Thickness and Density

Such parameters are those basic characteristics that significantly affect the energy efficiency of building materials. Aerated concrete with a lower density will have a minimum coefficient of thermal conductivity, respectively, the thickness of the wall created on the basis of such blocks will have to be artificially increased.The reverse side of the medal is low strength, which will affect the reliability and strength of the entire structure. Professionals advise entrusting such calculations to a highly qualified heat engineer.

Frost resistance

In the production of construction work in areas with very cold winters, an important indicator of the block material will be its resistance to low temperatures. It also has its own marking and is indicated by the letter "F". Specifically, for the middle zone of the Russian Federation, an indicator of 50 to 100 units is recommended, for more southern regions it will be 15-25 units. But most often, products with an indicator of 25-50 units are used, and if necessary, they are simply heavily insulated additionally.
