Calcium aluminate

1. Description

amorphous calcium aluminate, non crystalline calcium aluminate, non crystallized calcium aluminate, amorphous C12A7, ACA, concrete accelerator, CAS No. 12042-68-1, cement addititve, shotcrete additive, concrete additives

ACA are the white-green grains and balls. Generally, the grains are ground into fine powder, the ACA powder and OPC (ordinary portland cement) are formulate into Rapid-hardening Mortar and Self-leveling mortar etc. With good performance of rapid strength and little dry shrinkage.

It is a special raw material for concrete and cement.

It can make the rapid setting time, good strength in concrete and cement. It is mainly used in shotcrete, concrete ground hardening and rapid setting etc.

CAS No. 12042-68-1
