Amorphous calcium aluminate / concrete additive / cement additive

Description：
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.
 
Amorphous Calcium aluminate advantages:
1、Accelerated and rapid harding
2、De ng against leakage
3、High-strength and super high-early strength;
4、Low profile;
5、Enhanced persistence,
6、Good adhesion
 
Non-crystalline calcium aluminate usages:
 
1、Accelerated and rapid harding as cement accelerator,mainly in tunnels,underground engineering
 
2、De ng against leakage in nuclear power plant and other major projects
 
Specification:
Physical and chemical indexes of non-crystalline calcium aluminate:
