Rapid Hardening Cement C12A7 Concrete Mix Accelerator For Cement In Underground Engineering.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.
Physical and chemical indexes of non-crystalline calcium aluminate:
|Non-crystallization rate||Over 95%|
|Specific surface area||5000-6000 m2/g|
