FIELD: construction.
SUBSTANCE: invention relates to the production of foam concrete for construction. Method of manufacturing products from non-autoclaved foam concrete includes preparing the raw mix by mixing Portland cement, mineral aggregate, water and separately prepared foam, pouring the foam concrete mass into molds, holding to a set of cutting strength, cutting arrays into products. Surface of the product is treated with a composition containing, in wt.%: Silica sol with a concentration of 3 % 45–55 and synthetic latex 45–55.
EFFECT: invention will improve the quality of products, reduce their water absorption and increase compressive strength.
