FIELD: construction materials.
SUBSTANCE: invention relates to the construction materials industry and can be used for fire protection of building constructions. Fire resistant fiber vermiculite pumice concrete raw mix contains, by weight: portland cement 8.4–13.2; foamed vermiculite of fraction 0.63–5 mm 10.23–13.25; volcanic pumice of fraction 0–0.63 mm 21.86–25.44; saponified wood tar 0.08–0.13; quicklime 8.1–13.3; building gypsum 0.4–0.6; basalt fiber 1.0–1.5; water is the rest.
EFFECT: technical result is an effective increase in the fire resistance of building structures due to the expansion of the raw material base, strength improvement with the simultaneous decrease in the cost of the coating.
