| Abstract: | Sintering of electrolysis manganese slag-shale-coal ash for brick was done in purpose of treating solid waste generated in Zhubugang District,Xiangtan City.Effects of composition,sintering temperature and holding time on the performance of brick were investigated.Structure and characteristics of the brick were detected by SEM,EDS,comprehensive strength tests,TCLP,DTA and XRD.Results showed that the optimal sintering process achieved at 1 000 ℃ sintering for 2 h in the ratio of electrolytic manganese slag,shale and coal ash of 4:5:1.Under the conditions,the compressive strength of the brick reached 22.64 MPa.Manganese concentration in the leachate reduced from 451.08 mg/L to 0.676 3 mg/L,which are in line with the national standard regulations. |
