FIELD: manufacture of building materials.
SUBSTANCE: invention concerns manufacture of aerated concrete suitable for structural-insulation parts used in construction of residential, public, and industrial buildings up to two floors high and having no internal framework. Composition contains, wt %: cement, non-washed and non-ground sand 31-42, aluminum powder 0.10-1.0, caustic soda 0.05-0.45, and water - the balance. Manufacture of aerated concrete comprises dissolving alkali component (caustic soda) in water at 65-90°C, stirring resulting solution with added thereto cement, sand, and aluminum powder, pouring thus obtained mix into mold, and keeping it therein to swell and harden.
EFFECT: increased strength of aerated concrete and reduced manufacture expenses.
