    Amorphous C12A7 Concrete Mix Accelerator Calcium Aluminate For Silicate Cement

    Amorphous C12A7 Concrete Mix Accelerator Calcium Aluminate For Silicate Cement


    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 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.
