COMPOSITION FOR PRODUCING HEAT-RESISTANT CONCRETE Russian patent published in 2016 - IPC C04B28/34

Abstract RU 2580536 C1

FIELD: construction.

SUBSTANCE: invention relates to construction materials, particularly to production of heat-resistant concrete based on chemical binders. Composition for producing heat-resistant concrete contains following component ratio, wt%: spent catalyst IM-2201 10-15, crushed rock 33-40, sand 10-13, H₃PO₄10-15, calcium-containing slag from production of medium-carbon ferrochrome containing, %: Cr₂O₃ - 4.91; SiO₂ - 26.38; Al₂O₃ - 5.63; FeO - 1.0; CaO - 49.18; MgO - 12.9; 24-30.

EFFECT: technical result consists in improvement of ultimate compression strength and heat resistance of refractory concretes.
