Brief description of refractory of cement CA50
The rheological properties of CA50 are applicable to all types of casting methods, especially casting and spraying. Recommended for applications with fast hardening properties and excellent mechanical properties.
Features of cement CA50-A700
CA50-A700: Compared with A600, A700 has low impurity content, stable hardening performance and fast strength development. It is recommended to be mainly used for low cement castable.
