The Phases and Structure of Calcium Aluminate Cements (CACs)
11.09.2002· Phases of Calcium Aluminates Calcium Mono-Aluminate. The main hydraulic mineral in CAC is calcium mono-aluminate (CA). The hydration of CA contributes to the high initial strength of CACs. CA is a monoclinic phase and pseudo-hexagonal, and its space group is P21/n, Z = 12, and D x = 2.945 g/cm 3.
