高钛型高炉渣透水砖的制备及性能表征
Preparation and Characterization of Pervious Brick with High Titanium Blast Furnace Slag
摘要
Abstract
This is an essay in the field of ceramics and composites.In order to realize the reuse of solid waste of high titanium furnace slag and solve the problem of making permeable bricks with large amount of high titanium furnace slag,the permeable bricks were prepared by forming and sintering the billet with the furnace slag as aggregate,kaolin and potassium feldspar as binder and melting aid.TG-DSC comprehensive thermal analysis and SEM morphology analysis were used to study the thermal properties of the material and the morphology change at high temperature.The effects of the proportion of furnace slag and auxiliary materials,the particle size of furnace slag aggregate,forming pressure,sintering temperature and holding time on the properties of permeable bricks were discussed,and the suitable preparation process parameters of permeable bricks were determined.The results show that the ratio of blast furnace slag:Kaolin:K Feldspar(mass fraction)is 75∶10∶15,the molding pressure is 10 MPa,the sintering temperature is 1095 ℃,and the holding time is 3 h,the permeability Coefficient of permeable brick is 0.064 cm/s,the flexural strength is 12 MPa,which has the characteristics of high permeability and high strength,and meets the requirements of"Permeable pavement brick and permeable pavement board"(GB/T 25933-2010).关键词
