Concrete Mix Accelerator Amorphous C12A7 Rapid Setting For Shotcrete Accelerator
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.
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.
non-crystalline calcium aluminate:
|Non-crystallization rate||Over 95%|
|Specific surface area||5000-6000 m2/g|
