The authors describe the results of studying medium-cement heat-resistant concrete with an additive of waste catalyst (WC) that is generated at oil-processing plants and compare them with traditional microsilica and reactive alumina additives. Certain specifics of reactions between aluminate cement Gorkal-40 and the WC are identified, which accelerate the setting and hardening of concrete. The WC additive facilitates the formation of anorthite in the concrete matrix, which has a positive effect on the thermal resistance of heat-resistant concrete.
