May 01 1982 · Calcium aluminate cement concretes are not rapid setting. They are however rapid hardening that is they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours using a water spray or fog ponding wet burlap or a curing membrane.

Calcium Aluminate Cement-Rongsheng Unshaped Materials
Brief Description. Calcium aluminate cement is a cement containing calcium monoaluminate (CaO·Al 2 O 3 ) or calcium aluminate (CaO·2Al 2 O 3 ) as the main mineral component. It is made of natural bauxite or industrial alumina and calcium carbonate (limestone) in a certain proportion calcined or electrofused and also made by mixing iron bauxite and limestone.

Calcium Aluminatean 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.
