Description of Refractory Cement CA50 A900

A900 product is produced with selection of high purity materials, the alumina content of A900 is higher than other grades, and impurity oxides as like SiO2, Fe203 content is lower than that of A600 and A700. So, it is widely recommended for applications where stable hardening properties, good working ability and excellent mechanical performance are required.
