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.
