Product Description






High aluminum cement is a kind of powder hydraulic cementmaterial with alumina content of about 50% in clink and calcium aluminate as the main material, also known as refractory cement, which can be made into low cement high aluminum castable for construction or repair of various high strength heat preservation or acid erosion resistance of kiln and furnace.
Application of High Alumina Refractory Cement
High aluminum cement is mainly used to configure refractory castables such as high aluminum and low cement, which can build or repair kilns or furnaces with insulation or high temperature erosion.
