Abstract Cement, the most used building material amounts to an annual world production of 3.5 Gt. Sulfobelite cements, SB, require lower kiln temperature and emit less CO2, compared to Ordinary Portland cement, OPC. The main difference of SB from OPC is the reduction of alite (CaO)3SiO2, the increase of belite (CaO)2SiO2 and the formation of yeelimite (CaO)4(Al2O3)3SO3, …
Bauxite is an aluminous rock containing aluminum hydroxide as the main constituent and iron oxide, silica, and titania in varying proportions. Bauxite cement is developed by fusing calcium bearing material, such as limestone, and aluminum bearing material, such as bauxite. It has restricted applications owing to its relatively high costs.
