Calcium Aluminate Cement CA50-A700 Refractory 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 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. Also got the good evalution and long-term repo. We are waiting for long term cooperation with you.
