Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH, ranging from 11.4 to 12.5, is reduced as compared to OPC (Goñi et al., 1991 ). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.
