Product Description
Amorphous over 95% Amorphous calcium aluminate enhanced persistence cement additive for calcium aluminate cement
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.
Specification:

Amorphous Cacium aluminate advantages:
l Accelerated and rapid harding
l Defending againt leakage
l High-strength and super high-early strength;
l Low profile;
l Enhanced persistence,
l Good adhesion
Non-crystalline calcium aluminate usages:
l Accelerated and rapid harding as cement accelerator,mainly in tunnels,
underground engineering
l Defending againt leakage in nuclear power plant and other major projects
Remark: specification and size can be optimized by per customer' requirement
