FIELD: manufacture of building materials; production of cellular concrete.
SUBSTANCE: proposed molding sand produced on base of regional raw component contains Portland cement, aggregate, filler, foaming agent, modifying additive and water; used as aggregate is quartz sand and used as filler is ground gauze at specific surface of 3700 cm2/g; used as foaming agent are alkyl sulfates of primary fatty alcohols; used as modifying additive is additive on base of condensed phenols at the following ratio of components, mass-%: Portland cement, 36.74-43.94; quartz sand, 18.75-19.1; ground molding box, 0-6.37; foaming agent, 0.065-0.067; additive, 0.022-0.023, the remainder being water.
EFFECT: enhanced strength characteristics; low cost of material due to use of regional raw material.
