High Alumina CementComposition Uses Applications
High Alumina Cement. High alumina cement is the same as rapid hardening cement which attains ultimate strength in a short period. Unlike Ordinary Portland cement It contains calcium aluminates instead of calcium silicates. HAC is manufactured from chalk or limestone and bauxite. It contains 35 of Alumina and a balance of lime components.

Question on High Alumina Cement (HAC)
Answer. High Alumina Cement (HAC) differs from Portland cement being composed calcium aluminates rather than calcium silicates. 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.
