CRUDE MIXTURE FOR MAKING FIREPROOF COATING

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to the industry of construction materials and can be used in industrial and construction organisations for fireproofing building structures. The crude mixture for making fireproof coating contains the following in wt %: gypsum 14.6-21.7; foamed vermiculite 33.4-50; wastes from sawing volcanic tuff 22.5-33.3; caustic lime 7.83-11.5; saponified wood resin 0.07-0.1. ^ EFFECT: increased fire-resistance of building structures due to reduced thermal conductivity of fireproof concrete in case of fire with simultaneous reduction of specific consumption of gypsum without reduction in strength. ^ 3 tbl
