FIELD: building materials production. SUBSTANCE: dry and liquid ingredients are mixed at room temperature, their ratio being 45-80:29-60 respectively. Frothing and hardening are carried out at room temperature. Dry mixture is prepared of ferrosilicium and aluminosilicates (their quantity being not less 80 %), at their ratio 1:(0.67-2.0) respectively. Dispersity of ferrosilicium having silicium content 65-90 % is 4000-6000 cm2/g; dispersity of aluminosilicates is not more 2000-3000 cm2/g. Liquid component is prepared of liquid glass (its density being not less 1.43 g/cm3 and its modulus being 2.3-2.4), fluorine-comprising component and sodium hydroxide, their ratio being 1: (0.05-0.4):(0.05:0.4) respectively. Mixture comprises, wt.p.: ferrosilicium, 25-30; aluminosilicate, 20-50; liquid glass, 25-40; fluorine-comprising component, 2-10; sodium hydroxide, 2-10. Finely ground filler is added additionally, its quantity being 25-65 weight parts. Alternative method for production of cellular heat resistant concrete is also given. Desired concrete has low bulk density, improved moisture resistance, high heat resistance and heat insulation. EFFECT: improved quality of desired product. 5 cl, 1 tbl
