【摘要】：根据有色金属尾矿的矿物组成,利用机械与化学改性对尾矿的活性进行激发,进而作为硅质材料制备B06级蒸压加气混凝土砌块,并研究了尾矿矿物特性、颗粒细度及蒸压养护时间对制品力学性能的影响。研究表明,在尾矿微粉、石灰、水泥、石膏质量比为65∶20∶12∶3,以30%铜尾矿与35%金尾矿复掺,尾矿粉磨时间20 min,蒸压温度180℃、养护时间8 h的条件下,能够制备出满足A3.5、B06级别的加气混凝土制品。
[Abstract]:According to the mineral composition of non-ferrous metal tailings, the activity of tailings was excited by mechanical and chemical modification, and then the B06 autoclaved aerated concrete blocks were prepared as siliceous materials, and the characteristics of tailings minerals were studied. Effects of particle fineness and curing time of autoclaved pressure on mechanical properties of products. The results show that when the mass ratio of tailing powder, lime, cement and gypsum is 65: 20: 12: 3, the tailings are mixed with 30% copper tailings and 35% gold tailings, the grinding time of tailings is 20 min, the autoclaving temperature is 180 鈩，
