摘　　要：为解决锰渣利用率低的问题，以锰渣为主要原料，加入胶凝材料和早强激发外加剂，生产具有一定保温性能的轻质微孔墙材。重点改进了墙材的制作工序和保养工艺。当质量配比为锰渣85％、P·Ⅱ42．5水泥12％、硅灰2％、剑麻纤维材料1％时，辅以适量化学激发剂和聚羧酸减水剂，可以制得非承重保温墙材，其28d抗压强度为2．0MPa，导热系数为0．12～0．13W／（m·K）。To solve the problem of low utilization of ferromanganese slag, lightweight porous wall material with certain insulation pefformauce is prepared by taking ferromanganese slag as raw material and adding cementitious materials and early-strength activator. The manufacturing process and maintenance technique of wall materials are improved. When the mass ratio of ferroman- ganese slag,P·Ⅱ42.5 cement, silica fume and sisal fiber is 85%, 12%,2%,and l%, combined with certain amount of chemical activators and poiycarboxylate water reducer, non-load-bearing insulation wall materials can be obtained,the 28 d compressive strength is 2.0MPa,and thermal conductivity is 0.12-0.13 W/（m-K）.
