FIELD: construction.
SUBSTANCE: invention can be used by industrial and construction organisations for fireproofing of building structures. Fire-retardant crude mixture for making of fireproof coating contains, MP: portland cement - 8.4-13.2; expanded vermiculite of 0.16-5 mm fraction - 16.47-21.32; volcanic ash of 0-0.16 mm fraction - 9.2-15.2; basalt fibre - 1.0-1.5; wood saponified resin - 0.08-0.13; unslaked lime - 8.1-13.3; gypsum plaster - 0.4-0.6; water - the rest.
EFFECT: higher fire resistance of building structures, reduced specific consumption of portland cement, increased strength of vermiculite concrete, higher crack resistance and fire-retardant properties of the coating during fire, wider raw material base.
