Gas Blocks' Hidden Flaw: Hairline cracks signal structural collapse

Hairline cracks appearing on walls a few years after moving into a new home often signal a fundamental structural failure rather than a surface defect. For residents of aerated concrete (gas block) homes, these cracks usually indicate that the porous material is being forced to perform a structural role it cannot sustain without specific reinforcement. The Structural Vulnerability of Aerated Concrete Aerated concrete is valued for its thermal insulation and light weight, but it is significantly more brittle than traditional brick. It reacts sharply to point loads and structural shifts. When heavy roof loads or floor slabs rest directly on these blocks, the material often fails under the pressure. Engineer Aleksey Tikhonov told Pravda.Ru that treating gas block as a direct substitute for concrete is a mistake. According to Tikhonov, the material's primary function is thermal protection; without additional reinforcement, it cannot support the full weight of a building and will crack under uneven loads.
