【LOW CEMENT CASTABLES】

The low cement castable was developed to improve the characteristics of castable at high temperature. Not only the dispersion of cement can be improved, but also the quantity of the cement and the additional water can be reduced. The low cement castable has low porosity、high erosion resistance、 spalling resistance and good high temperature strength refractories.
