High Density Refractory High Alumina Cement With Tightly Package

High Density Fire Ca80 Aluminate Cement Powder With Tightly Package

High Alumina Cement (previously called bauxite cement) is a kind of grinding hydraulic cementing materials with clinker about 50% alumina content and has calcium aluminate as the main material, which is also called refractory cement, which can be made to low cement high alumina castable to build or repair all kinds of furnace and kilns for thermal insulation or acid erosion resistance with high strength.
