COMPOSITION FOR PRODUCING HEAT-RESISTANT COMPOSITES Russian patent published in 2017 - IPC C04B28/34 C04B14/24 C04B111/20 

FIELD: construction.

SUBSTANCE: method is carried out by adding microsilica from the production of ferrosilicon to the composition at the following component ratio, wt %: spent catalyst IM-2201 10-15; crushed stone with the fraction of 5-10 mm 33-40; H₃PO₄ 10-15; aluminium-chromium waste of aluminium alloys etching 24-30; microsilica from the production of ferrosilicon 10-13.

EFFECT: increased mechanical strength and thermal resistance of heat-resistant composite, industrial waste utilization, environmental protection, expansed raw material base for building materials.
