Product Name: Calcined Bauxite Used for High Alumina Cement Model NO.: SNC-85 Al2O3: 85% Fe2o3: 2.0% Trademark: Sinocean Transport Package: 1mt Jumbo Bag or as Per Buyer? S Requiremen Specification: Al2O3: min 85% Origin: China HS Code: 2606000000 Product Description Cement Grade BauxiteCalcined 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 10:1. And the maximum acceptable amount of Fe2O3 allowed in the low iron oxide type may reach 3%, although it is commonly max. 2.5%.ApplicationCalcium aluminatecement, alumina cementsor 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. 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 24 hours.SINOCEAN AvailableCementGrade BauxiteSpecificationItem SNC85 SNC82Al2O3(%) 85.0min 82.0min SiO2(%) 8.0max 10.0 max Fe2O3(%) 2.0 max 2.0 max TiO2(%) 4.0 max 4.0 max Moisture0.5 max0.5 max Available grain size5-50mm(passing min 90%), or as customer's request.Package1MT Jumbo bagStandard exporting package for sea transportation or air deliverySpecial packing requirement is acceptable
