Method for preparing high-strength cementing material from lead-zinc smelting slag
The invention discloses a method for preparing a high-strength cementing material from lead-zinc smelting slag, and belongs to the field of solid waste green treatment and resource utilization. The method comprises the following steps: mixing lead smelting slag and a sodium hydroxide solution in proportion, and ball-milling; fly ash is subjected to ball milling, and fly ash subjected to ball milling is obtained; mixing the ball-milled lead smelting slag, the ball-milled fly ash and an exciting agent according to a certain proportion, and stirring to obtain slurry; and pouring the slurry into a mold, and carrying out compression molding under a certain pressure. And finally, maintaining the formed green body to obtain the lead smelting slag-based geopolymer. The prepared lead smelting slag-based geopolymer has the advantages of high lead smelting slag doping ratio, good heavy metal curing effect, high mechanical property and the like.
一种铅锌冶炼渣制备高强度胶凝材料的方法，属于固废绿色处置与资源化利用领域。首先，将铅冶炼渣与氢氧化钠溶液按比例混合、球磨。将粉煤灰进行球磨，得到球磨后的粉煤灰。将球磨后的铅冶炼渣、球磨后的粉煤灰和激发剂按一定比例混合、搅拌，得到浆料。将浆料浇注到模具中，并在一定的压力下压制成型。最后，成型后的坯体经养护后得到铅冶炼渣基地质聚合物。本发明制备的铅冶炼渣基地质聚合物具有铅冶炼渣掺比高、重金属固化效果好、力学性能高等优点。
