Low Cement Castable High Alumina Corundum Material Refractory Castable Material
Low cement catable is developed on the basis of clay and refractory castables by Kerui Group. It mainly includes low cement, super low cement, no cement or ultra micro powder+sol, etc. Many advantages of refractory castables gather to it, such as high density, low apparent porosity, high strength, low abrasion, thermal shock resistance, corrosion resistance, etc.
