Calcium Aluminate - an overview | ScienceDirect Topics

HAC is a type of calcium aluminate cement, which is manufactured by fusing limestone and bauxite, rather than the limestone and clay/shale used for Portland cement. HAC was used in structural concrete mainly from the 1950s to the early 1970s, most commonly in the manufacture of precast, prestressed concrete beams.

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.
