FIELD: construction.
SUBSTANCE: invention is intended for making foam concrete, also can be used for production of heat-insulating materials directly at construction site. Raw mixture for making foam concrete contains, wt%: portland cement 63.65-65.93, foaming agent 0.44-0.51, carbon additive - pyrolysis soot with particle size within 10-3-10-6 mm 0.66-0.72, water to produce foam 18.79-19.21, water for tempering 14.18-15.91.
EFFECT: high compression strength and low coefficient of thermal conductivity of foam concrete obtained from the mixture.
