Preparation and Performance Research of High Strength Building Ceramics from Low Aluminum Raw Materials at Low Temperature
High strength building ceramics are prepared from slag,steel slag and shale with low-aluminum content as raw materi-als at low temperature.The effects of slag,steel slag and shale on flexural strength,water absorption and bulk density of ceramic body were studied by XRD,XRF,SEM-EDS and other characterization methods.The results show that when the dosages of slag,steel slag and shale are 55 wt.％,10 wt.％and 45 wt.％respectively,the firing system is at 1 120 ℃ for 30 min,the comprehen-sive performance of the sample is the best,its flexural strength is 85.91 MPa,water absorption is 0.35％and bulk density is 2.37 g/cm3.The main crystalline phases of ceramic body are anorthite,diopside and β-quartz.
