Commercial production of calcium aluminate cement (CAC) from bauxite and limestone has been developed by Lafarge, France, by a fusion method since 1908 .
CAC is subdivided into pure calcium aluminate cement and alumina cement containing small amounts of SiO2 and Fe2O3.
CAC, with its rapid hardening, early strength, impermeability, resistance to corrosion, etc. due to the high Al2O3 content, is commonly used in the refractory industry [2, 3]. Because the spinel can absorb FeO, MnO, TiO2 and V2O5, this improves the slag viscosity and slag penetration. High alumina cement (HAC)...
