Product Description

High Alumina Refractory Cement Calcium Aluminate Cement A600 A700 A900 Ca70

High Alumina Cement

 

 

The High Alumina Cement also well known as calcium aluminate cements, 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. The heat resistance cement can be used for making refractory castable and other high temperature resistant products.
CH Refractories with 500T manufacturing capacity of refractory alumina cement one day to make sure delivery to customers in time. The High Alumina 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.

 

High Alumina Cement with high strenght and purity, are widely used to manufacturing different levels refractory castable or use directly in high temperature kiln and furnace.

Applications of High Alumina Cement:
High alumina cement is mainly used to configure refractory castable such as high alumina low cement castable which can build or repair furnace or kiln for heat insulation or high temperature erosion.

 

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.

 

Advantages of CH series High Alumina Cement:
●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
