FIELD: manufacture of building materials.
SUBSTANCE: object of invention is manufacture of building materials with foamed concrete properties. Building mortar containing cement, water, and stearate as foaming agent contains, according to invention, 23-29% of Portland cement, 5-9% of sodium stearate, 7-11% water, and additionally55-61% of filler composed of CaCO3 and MgCO3 at weight ratio 65:35.
EFFECT: reduced heat conduction and improved heat-reflecting properties of foamed concrete.
