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.
