COMPOSITION FOR MAKING HEAT-RESISTANT COMPOSITES Russian patent published in 2016 - IPC C04B28/34 C04B18/14 C04B111/20 

FIELD: construction.

SUBSTANCE: invention relates to construction materials, particularly to production of heat-resistant composites (concrete) based on chemical binders. Technical result of the invention is high ultimate compression strength and heat resistance of heat-resistant composites, which is achieved by adding to the composition of sludge and dust by-products from production of low-carbon ferrochrome in the following proportions, wt%: spent catalyst IM-2201 10-15, crushed rock 33-40, H₃PO₄ 10-15, aluminium alloy 24-30, sludge and dust by-products from production of low-carbon ferrochrome 10-13.

EFFECT: technical result is high ultimate compression strength and heat resistance of heat-resistant composites.
