What is calcium-aluminate cement?

Calcium-aluminate cements are primarily used for high heat refractory appliions. Other uses include moderate acid-resistant appliions, high-early-strength and quick-setting mixtures, and as part of the expansive component in some shrinkage-compensating cements.

CIMENT FONDU - FONDU TECHNOLOGY

The first ever alumina cement that kickstarted this range’s great adventure, CIMENT FONDU® is the pioneer of alumina cements. When you use CIMENT FONDU ® to speed up setting for your concrete or to make concrete that is resistant to extreme conditions (heat, cold, abrasion, chlorides, etc.), the quantity must be 400 kg/m3 of cement and the water/cement ration must be a maximum of 0.40.

Expansive Cement - an overview | ScienceDirect Topics

In terms of powder diffraction files published by JCPDS [49,50], calcium aluminate sulfate (3CaO·3Al 2 O 3 ·CaSO 4) is a ternary compound. It is the main constituent in sulfo-aluminous clinker, which is used as an expansive agent in manufacturing expansive cement .

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.
