Generally, the grains are ground into fine powders. The Amorphous calcium aluminate powder and OPC (ordinary Portland cement) and CSA cement are formulated into Rapid-hardening Mortar and Self-leveling mortar etc. With good performance of rapid strength and little dry shrinkage.

Application of the Amorphous Calcium Aluminate:

Shotcrete
Concrete accelerator
Rapid setting, rapid hardening cement
Concrete ground hardening
Rapid-hardening Mortars and Self-leveling mortars etc.
