FIELD: construction.
SUBSTANCE: invention relates to production of construction articles and can be used in production of aerated concrete structural insulating blocks. For this purpose, the crude mixture for aerated concrete includes CEM I 42.5 B Portland cement, thermal power plant flue ash – 4 of Omsk, aluminium paste, construction gypsum, detergent powder, water, and also contains polypropylene fibre with diameter of 0.33–0.38 mcm in lengths of 5–10 mm, length of 12–15 mm, polyamide fibre with diameter of 0.30–0.35 mcm in lengths of 10–15 mm, 15–30 mm long, basalt fibre with diameter of 0.8–1.0 mcm in lengths of 6–12 mm, length of 18–24 mm at a certain ratio of components.
EFFECT: improved quality of aerated concrete in terms of heat conductivity and frost resistance, resistance to crack development.
