Effect of microsilicon on the properties of heat-resistant castable with chamotte scrap filler

Effect of microsilicon on the properties of heat-resistant castable with chamotte scrap filler Chamotte scrap with an elevated water absorption is used as a filler in low-cement heat-resistant concretes (castables) of the new generation.

Abstract

Chamotte scrap with an elevated water absorption is used as a filler in low-cement heat-resistant concretes (castables) of the new generation. The studied castable compositions contain from S to 16% microsilicon. The effect of heat treatment of the castable to up to 1300°C on the change in its density, the ultimate compressive strength, deformation, and the speed of an ultrasonic pulse is determined. It is shown how microsilicon affects the setting of mortar and a hypothesis is made on the mechanism of the interaction of thin-phase components in the studied composition.
