Low Cement Castable Refractory
1. Low cement refractory castable refer to castable refractory materials with less t han 8% calcium aluminate cement. It is required that the content of CaO in the castable is less than 2.5%, and its main type is low cement (Cao content 1%~2.5%), ultra low cement (1% CaO content)and no cement ( CaO ≤0.2%) refractory castable.
2. It has the characteristics of high density, low porosity, high strength, low wear, heat resistance and corrosion resistance, also has the volume stability and low construction water consumption.
