What is calcium-aluminate cement?

A. Calcium-aluminate cements are hydraulic cements obtained by pulverizing a solidified melt or clinker that consists predominantly of hydraulic calcium aluminates formed from proportioned mixtures of aluminous and calcareous materials. They are generally divided into three groups based on the alumina and iron oxide contents (Low Purity
