Description

High alumina cement is obtained by mixing calcining bauxite and lime with clinker during the manufacturing process of OPC. 

To be considered high alumina cement, the total amount of alumina content should be at least 32%, and the ratio of the weight of alumina to lime should be kept between 0.85 to 1.30. 

The most common uses are in constructions that are subject to high temperatures like a workshop, refractory, and foundries.
