What 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
