Product Description

high temperature Calcium Aluminate Cement CA50-A700 Refractory Cement Powder High Alumina Castable Refractory

High Temperature Calcium Aluminate Cement CA50-A700 Refractory


The calcium aluminate cements CA50-A600 A700 A900, and high alumina castable refractory cement. Generally there are 4 grades of refractory cement according to Al2O3 content and strength, A600, A700,A900 and CA-70. 


Calcium aluminate cement is mainly used as a binder for refractory castables and ejectors. Clay, high aluminum castable use common calcium aluminate cement as binder, rigid jade, mullite, chromium containing rigid jade, spinel castable use pure calcium aluminate cement as binder.

CH Refractories with 500T manufacturing capacity of High Alumina Refractory Cement one day to make sure delivery to customers in time. The refractory aluminum cement will be packaged into three layers 25 kg bag and then into two layers moistureproof polytene jumbo bags directly from the manufacturing line to protect high temp refractory cement from wet air.


The calcium aluminate cements CA50-A600 A700 A900 manufactured by CH Refractories with stable quality and best price. The cement are exported to many countries regularly, such as Saudi, Malaysia, Indonesia and so on. We are waiting for long term cooperation with you.

Advantages of CH calcium aluminate cements CA50-A600 A700 A900:
●Fast setting at high temperature
●Increase castable strength
●Can replace castable when using
●Can be added to both heavy and light castable
● Biological acid erosion
● High temperature resistance
●Sulfate corrosion resistance


Packaging & Shelf Life
Refractory cement is available palletized in 25kg bags, or 50kg bags. super sacks.
Refractory cement packaging is designed to protect it from humidity. However, as with all hydraulic binders, it is recommended that Refractory cement not be placed outdoors or in direct contact with the ground. When correctly stored in dry conditions, the properties of Refractory cement will remain within specification limit for at least 6 months. In most cases, its properties will be retained for over a year.
