FIREPROOF RAW MIX

摘要

FIELD: construction. ^ SUBSTANCE: invention is related to industry of construction materials and may be used by industrial and construction enterprises for fire protection of construction elements. Fireproof raw mix includes the following components, wt %: Portland cement 11.9-35.8; foamed vermiculite 12.3-16.8; wastes of volcanic tuff sawing 5.8-9.1; saponated wood tar 0.08-0.13; quicklime 0-17.9; construction gypsum 0-0.7; the rest -water. ^ EFFECT: improved fire resistance of construction elements due to reduction of heat conductivity of fireproof concrete during fire with simultaneous reduction of specific consumption of Portland cement without loss in strength. ^ 1 cl, 3 tbl
