FIELD: construction.
SUBSTANCE: invention is related to construction materials, namely to fire resistant light concrete mixes on the basis of porous fillers. Raw mix for fire resistant structural-heat insulation concrete contains the following components, wt %: 15-20 of binder - high-aluminous cement, 23.95-24.37 of foamed slag with fraction of 10-20 mm, 15.16-18.55 of foamed slag with fraction of 5-10 mm, 37.5-42.5 of foamed slag with fraction of less than 2 mm and 0.2-0.8 of plasticising agent lignosulphonate LSTM-3; water-solid ratio - 0.2-0.35. Composition of raw mix provides for production of light fire resistant concrete with temperature of application of up to 1200°C.
EFFECT: production of concrete with improved physical-mechanical and thermal parametres for lining of metal surface of thermal units at the temperature of up to 1100-1200°C.
