FIELD: construction.
SUBSTANCE: invention relates to the industry of construction materials and specifically to production of non-autoclave hardened cellular concrete with high coefficient of structural quality and low coefficient of heat conductivity. Crude mixture for preparing foam concrete contains, wt. %: portland cement 28.9–39, natural sand 41–45, foaming agent 0.013–0.015, water 0.53–0.59, complex additive - finely ground lime 5–6, natural diatomite 9–10, glass fiber 4.
EFFECT: technical result is higher compression and tensile strength, increased porosity, reduced heat conductivity.
