High Alumina refractory Cement Calcium Aluminate Cement CA50-A600 Refractory Cement Powder

High Alumina Refractory Cement

The High Alumina Refractory 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 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.
As professional manufacturer and company of refractory aluminate cement since 1980, CH refractories company produces and provides customers with a varied range of high-tech calcium aluminate solutions benefiting from the highest performance and quality. The SECAR range offers a large choice of binders based on calcium aluminate technology for fire proof applications. Through its understanding of the customer's needs, CH refractories company has developed one of the widest ranges of aluminate cement for sale on the market.

Applications of High Alumina Refractory Cement:
High Alumina Refractory 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.

Advantages of CH series High Alumina Refractory 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

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.
