FIELD: construction.SUBSTANCE: invention relates to construction materials and can be used for making light concrete used in industrial and civil construction. Crude mixture for foam concrete contains, wt%: portland cement 46.10–48.60, sand with specific surface area S=200 m/kg 11.0–11.52, 25 % solution of polycarboxylate polymer CP-WRM, represented by a copolymer of acrylic acid and ethyl ester of methacrylic acid with pH value of 6, density ρ=1.033 g/cm, 0.42–0.46, granular foam glass with particle size of 1.25 mm and bulk density ρ=250 kg/m18.48–19.47, water 21.5–22.45.EFFECT: high compression strength and low coefficient of heat conductivity of foam concrete.1 cl, 1 tbl, 1 ex |
