Lead-zinc tailing-based alkali-activated cementing material and application thereof
The invention discloses a lead-zinc tailing-based alkali-activated cementing material and application thereof. The lead-zinc tailing-based alkali-activated cementing material comprises activated lead-zinc tailings, an auxiliary cementing material and an alkali activator, the activated lead-zinc tailings are obtained by sequentially performing thermal activation and mechanical activation on lead-zinc raw tailings, and the auxiliary cementing material is obtained by mixing slag, steel slag and desulfurized gypsum. The alkali-activated cementing material has a good fixing effect on heavy metals such as Pb and Zn in the lead-zinc tailings, has the characteristic of rapid hardening, has relatively good compressive strength after being formed, and can be applied to industrial production of roadbeds, buildings and the like. The preparation method of the auxiliary cementing material is simple and easy to implement, does not need special equipment, and is suitable for industrial production.
本发明公开了一种铅锌尾矿基碱激发胶凝材料及其应用，包括活化铅锌尾矿、辅助胶凝材料和碱激发剂；所述活化铅锌尾矿是由铅锌原尾矿依次经过热活化和机械活化得到，其中，辅助胶凝材料由矿渣、钢渣和脱硫石膏混合得到。该碱激发胶凝材料对于铅锌尾矿中的Pb、Zn等重金属具有良好的固定作用，且具有快速硬化特性，成型后具有较好的抗压强度，可应用于路基、建筑等工业生产中。该辅助胶凝材料的制备方法简单易行，无需特殊设备，适合工业化生产。
