High Alumina Cement - Concrete

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.
