FIELD: chemistry.
SUBSTANCE: invention relates to production of construction materials and can be used in making non-autoclave hardening foamed concrete. The raw mixture for making foamed concrete contains the following in wt %: portland cement 55.88-65.09, quartz sand with fineness modulus Mf of up to 1.8 14.1 - 29.31, keramsite sand with specific surface area of 2000 - 2500 cm2/g 10.06 - 22.67, Neopor foaming agent 0.32 - 0.37, aluminium powder 0.067 - 0.078, water up to "В/Т" = 0.35 - 0.45.
EFFECT: higher ultimate compression strength and strength-density ratio while maintaining low average density.
