FIELD: fireproof products industry.
SUBSTANCE: raw compound for fabrication of heat insulating concrete contains expanded aggregate, high-aluminous component, high-aluminous cement, kyanite and water. Besides it contains microsilica and plasticiser; aluminosilicate hollow microspheres are used as expanded aggregate and densely sintered bauxite as high-aluminous component with the following ratio of ingredients (mass.%): aluminosilicate hollow microspheres 15-40; densely sintered bauxite 40-56; high-aluminous cement 6-10; kyanite 5-20; microsilica 3-5; plasticiser (over 100%) 0.3-0.5; water (over 100%) 10-17.5.
EFFECT: increase of compression strength and obtaining fireproof heat insulating concrete that has no loss of strength in the whole range of working temperatures.
