Good frost resistance 55-60% Aluminate cement

Aluminate cement Introduction:

Aluminate cement is made of bauxite and limestone as raw materials, calcined calcium aluminate as the main component, the alumina content of about 50% of clinker, and then made of hydraulic cementitious material. High-alumina cement often yellow or brown, there are gray. The main minerals of Aluminate cement are calcium aluminate (CaO · Al2O3, abbreviated as CA) and other aluminates, and small amounts of dicalcium silicate (2CaO · SiO2). The colors are mostly gray and white.

Aluminate cement Features:

    Aluminate cement hardening quickly, one day to reach more than 80% of the label strength, three days to reach the label strength of 100%, and has good frost resistance, corrosion resistance, especially high refractory cement other unparalleled advantages.

Aluminate cement use and precautions:

    Generally not with Portland cement and other lime and other folded Ca (OH) 2 gel material directly.

    Aluminate cement refractory concrete, gravel ratio should be re-adjusted.

    After the construction should be timely water conservation, is strictly prohibited mixed soil dehydration chaotic and lose strength, water conservation for not less than three days.

    No additions shall be made to the Aluminate cement without trial.

    Large-scale structure of concrete pouring thickness of not more than 0.3 meters, or must be in the hardening of concrete to take cooling cooling measures.

    In the course of the process, if the feeling of condensation time is not appropriate, may be appropriate to use aluminate-specific quick-setting agent to adjust, adding the amount subject to experiment.

Aluminate cement main purposes:

    For the preparation of refractory concrete.

    For sulfate-resistant engineering.

    For the requirements of fast concrete and emergency repair works and early winter construction requirements of the special projects.

    Raw materials used in the manufacture of water purification agent (calcium aluminate powder).

Is the preparation of expansive cement, self-stressing cement and other special cement an important component.
