High Alumina Cement Introduce:
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.

Application of High Alumina Cement:
High temperature furnaces: used for lining industrial furnaces, such as high temperature furnaces in the steel, electrolytic aluminum, ceramics and cement industries.
Chemical industry: used in environments where corrosive substances are handled, such as linings for chemical storage tanks and pipelines.
Fire protection: used for fire protection layers in buildings to increase the fire resistance of buildings.
Rapid construction: used in projects that require rapid construction and early strength, such as emergency repairs and rapid construction projects.
