Main purpose of calcium aluminate cement
Prepare refractory concrete, refractory castable and unshaped refractory material.
Prepare expansive and self-stressing cement.
Make man made marble.
Non-load bearing sulfate resistant projects.
.Notice for calcium aluminate cement
Cement dosages should not exceed 20% when preparing refractory concrete.
Due to the concentrate early heat release, every casting thickness should not exceed 30cm. Water maintain immediately when concrete comes to rigid. Water conserve time should more than three days.
If steam curing, the curing temperature should not more than 50℃.
This cement is not adapted to alkaline environment, do not mix alkaline material such as lime.
