Conclusions
With the use of abrasion resistant aggregate (corundum or corundum-mullite compositions) the highest abrasion resistance, approximating to that of fired dense chamotte articles) during heating to 1100‡C is possessed by concretes having a phosphate bond and containing water glass.
Concretes based on high-alumina and aluminous cements around the critical temperatures have a low abrasion resistance, but at temperatures above 1100‡C as a result of the formation of a ceramic bond their abrasion resistance increases.
