Cement Grade Bauxite
Calcined bauxite used in high alumina or calcium aluminate cements range considerably in chemical composition. A high silica content hampers the rapid hardening property of the cement.This means the silica content must be controlled and a typical industry requirement is that the Al2O3:SiO2 ration is around *0:1.And the maximum acceptable amount of Fe2O3 allowed in the low iron oxide type may reach 3%, although it is commonly max. 2.5%.
Â
Application
Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker.Crushed or screened, it is used as an aggregate. The composition and colour - ranging from the purest white to jet black - depends on the proportion of each raw material.     Â
Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. This has the ability to harden very quickly: it forms a rigid solid within *4 hours.
