Calcium Aluminate Cement High Alumina

Question on High Alumina Cement (HAC)

Question on High Alumina Cement (HAC)

High Alumina Cement (HAC) differs from Portland cement, being composed calcium aluminates rather than calcium silies. Its rapid strength development made HAC popular from 1950 to 1970. However, mineralogical ´conversion´ sometimes caused reductions in concrete strength and increased vulnerability to chemical attack.

High Alumina Cement

High Alumina Cement is manufactured from limestone or chalk and bauxite (the ore from which aluminium is obtained). The two materials are crushed and fired together using pulverised coal as a fuel. The materials fuse together and the melt is transferred into steel pans. It is finally cooled, crushed and ground into a dark grey powder.
