Calculator of aerated concrete and building silicate blocks

Information on the purpose of the calculator

The online calculator of aerated concrete blocks is designed to perform calculations of building materials necessary for the construction of walls of houses, garages, utility rooms and other premises. The calculations can take into account the dimensions of the gables of the building, door and window openings, as well as related materials, such as mortar and masonry mesh. Be careful when filling in the data, pay special attention to the units of measurement.

Aerated concrete blocks are one of the types of cellular concrete, with air pores evenly distributed throughout the volume. The more evenly such pores are distributed, the higher the quality of the concrete itself.

The production of aerated concrete in the factory is a rather complex process. In addition to cement and sand, chemical gas-forming additives are used in production, the amount of which must be calculated with very high accuracy. After all the components are mixed, the whole array of aerated concrete is poured into special molds in which it increases in volume due to the release of gases.

The main feature of cellular concrete production is the hardening of poured concrete under pressure, in special autoclave chambers. This is necessary so that the air pores are evenly distributed throughout the volume. Production of high-quality aerated concrete is impossible without such chambers. After gaining the necessary strength, the entire array is cut into blocks of the required sizes.

As well as other types of blocks, aerated concrete is divided by density into:

• structural
- for the construction of load-bearing walls
• structural and thermal insulation
- for the construction of load-bearing walls of low-rise buildings
• thermal insulation
- for the construction of self-supporting walls

The disadvantages of this material include:

• High fragility
• The need to use special devices for attaching mounted objects to the walls
• High water absorption, resulting in an increase in the declared thermal conductivity
• Strong dependence of thermal insulation characteristics on the strength of blocks
• Using relative characteristics for advertising purposes

The following is a complete list of calculations performed with a brief description of each item. If you have not found an answer to your question, you can contact us by feedback.

General information on the results of calculations

• Perimeter of the building
- The total length of all the walls taken into account in the calculations.
• Total masonry area
- The area of the outside of the walls. Corresponds to the area of the necessary insulation, if such is provided by the project.
• Wall thickness
- The thickness of the finished wall, taking into account the thickness of the mortar seam. It may differ slightly from the final result depending on the type of masonry.
• Number of blocks
- The total number of blocks required to build walls according to the specified parameters
• Total weight of blocks
- Weight excluding mortar and masonry mesh. As well as the total volume, it is necessary to choose the delivery option.
• Quantity of concrete mortar for the entire masonry
- The volume of mortar required for masonry. The volumetric weight of the solution may vary depending on the ratio of the components and the additives introduced.
• Number of rows of blocks taking into account seams
- Depends on the height of the walls, the size of the material used and the thickness of the masonry mortar. Excluding pediments.
• Number of construction masonry mesh
- The required amount of masonry mesh in meters. It is used for reinforcing masonry, increasing the solidity and overall strength of the structure. Pay attention to the number of reinforced rows, the reinforcement of each row is specified by default.
• Approximate weight of finished walls
- The weight of the finished walls, taking into account all building blocks, mortar and masonry mesh, but without taking into account the weight of insulation and cladding.
• The load on the foundation from the walls
- Load without taking into account the weight of the roof and ceilings. This parameter is necessary to select the strength characteristics of the foundation.
