Amorphous C12A7 Concrete Mix Accelerator Calcium Aluminate For
Amorphous C12A7 Calcium Aluminate Aorphous Over 95% Concrete Mix
Accelerator For Silicate Cement.Amorphous calcium aluminate is the
basic raw material of a new Accelerator, its principal constituent
is the non-crystalline calcium aluminate. Appearance of light
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|
Packing:1 MT big bag or as per customer’s requirement
Amorphous Calcium aluminate advantages:
