January 8, 2021What is Aerated Concrete?
A construction material used for the production of blocks.
Composition of Aerated Concrete:
The primary raw materials used in the production of aerated concrete are:
- Lime
 - Sand
 - Water
 - Cement and gypsum (in small amounts)
 
As a pore-forming agent, aluminum powder is used, which, when reacting with calcium oxide, releases hydrogen gas.
The escaping hydrogen creates a porous structure within the material, and the air eventually fills these pores, making up 80% of the final volume of the material.
Advantages:
- Durability of constructed partitions
 - Low bulk density (lightweight)
 - Ease of installation
 - High dimensional accuracy of blocks and shapes
 - Favorable strength-to-density ratio
 - Good thermal properties, allowing for single-layer walls with high thermal insulation
 - Non-combustibility
 
Disadvantages:
- Brittle nature of individual elements
 - Requires careful protection against moisture during storage, transport, and after installation (moisture reduces thermal insulation and frost resistance)
 - Insufficient acoustic insulation in walls between residential units
