Refractory cement is made of high-quality bauxite and lime as raw materials, and is mixed into raw materials with appropriate ingredients in a certain proportion. After sintering, the clinker with aluminate as the main component is ground into fine powder to make a refractory hydraulic cementitious material. Usually mixed with refractory cement
Refractory cement is also called aluminate cement. Aluminate cement is a hydraulic cementitious material made from bauxite and limestone, which is calcined to produce a clinker with calcium aluminate as the main component and an alumina content of about 50%, and then ground. Aluminate cement is usually yellow or brown, and there are also gray ones. The main minerals of aluminate cement are monocalcium aluminate (CaO·Al2O3, abbreviated as CA) and other aluminates, as well as a small amount of dicalcium silicate (2CaO·SiO2).
