Calcium aluminate cement

Calcium aluminate cement is a high quality binder for refractory castable which is extensively applied in chemical industry, metallurgical industry, building material, petroleum industry, ceramic industry etc.
Quantity:

Calcium aluminate cement is used for manufacturing refractory castable or unshaped bulk refractory materials which are used in high temperature, high pressure condition.

It is a high quality binder for refractory castable which is extensively applied in chemical industry, metallurgical industry, building material, petroleum industry, ceramic industry etc.

Advantage: Quick-drying; High performance of heat resistance; High efficiency of construction
