Frost resistance and life. The cellular aerated concrete has a capillary-porous structure, thanks to which it has a relatively high frost resistance indicator compared to materials that have a capillary structure (concrete, brick, etc.). The service life of a building from aerated concrete is compared with a functional service life of the entire building and is designed for 100-150 years, but this is only a theory, since the history of the use of autoclave aerated concrete has only 85 years.
