Wholesale High Temperature Refractory Cement CA70 CA80 High Alumina Fireproof Cement
High Alumina Cement—often referred to as bauxite cement—is a specialized hydraulic binder made by grinding clinker that contains approximately 50% or more alumina (Al₂O₃). Its chief mineral phase is calcium aluminate, which sets it apart from Portland cement, whose chemistry revolves around calcium silicates. This distinct composition endows the material with outstanding characteristics, making it frequently called refractory cement.
One of its primary roles lies in the production of low-cement, high-alumina castables—advanced refractory concretes widely used to construct, reline, or repair high-temperature industrial furnaces and kilns across sectors such as metallurgy, ceramics, and waste incineration. These castables deliver superior thermal insulation, strong resistance to acidic slag attack, and sustained mechanical strength under intense heat.
Beyond high-temperature applications, High Alumina Cement also proves invaluable in time-critical engineering works, thanks to its rapid setting behavior and impressive early-age strength. It is therefore heavily relied upon in emergency repairs of pressurized defense structures, swift road restoration, and specialized rehabilitation tasks where minimizing downtime is essential.
