Effect of High Temperature Calcination on the Structure and Properties of Bauxite-based Homogeneous Clinker

摘要：

　　In this paper,it studies the effect of high temperature calcination on the structure and properties of bauxite-based homogeneous clinker by calcining at different temperatures with holding for different time.The results show that with the rise of calcination temperature and holding time,the volume density of bauxite-based homogeneous clinker increases and the apparent porosity decreases.After high temperature calcination,the linear expansivity of bauxite-based homogeneous clinker is smaller than that of the non-calcined ones.Whether or not calcined at high temperature,the thermal shock resistance of bauxite-based homogeneous clinker particles is good.The crystalline phases of bauxite-based homogeneous clinker are mainly mullite and corundum.There is more glass phase in the bauxite-based homogeneous clinker without calcination.After calcination at high temperature the content of glass phases decreases significantly,and the mullite crystals develop better forming the cross-network structure.
