Amorphous Calcium Aluminate

Amorphous Calcium Aluminate Details:
The mineral of amorphous calcium aluminate (non-crystalline calcium aluminate) is C12A7. The alumina content is about 50%. However, the appearance of amorphous calcium aluminate is different from crystaline calcium aluminate or CA. It looks like greenish (or a little blue color mixed) semi-transparent beads. 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.
