Chemical Name: Amorphous Calcium Aluminate

Synonyms: ACA, Non crystallized Calcium aluminate, amorphous C12A7,Concrete accelerator; Cement Accelerator Amorphous calcium aluminate 

CAS No.: 12042-68-1

Molecular Formula: C12A7

Properties:

Amorphous calcium aluminate is the basic raw material of a new Accelerator, its principal constituent is the non-crystalline calcium aluminate. Appearance of light gray-green powder.

 

Properties of amorphous calcium higher reactivity than the crystalline product, used in conjunction with silicate cement, can achieve a higher degree of responsiveness and efficiency. Non-crystalline calcium aluminate reacts unexpectedly fast with plaster and water to produce ettringite; adds its appropriate to ordinary silicate cement, the initial setting in less than a minute to complete. Addition of ettringite structural stability, good strength. While ettringite volume expansion, formation of prestressed concrete and shrinkage resistance.
