Alkali-activated copper-nickel slag cementing material and preparation method and application thereof
The invention provides an alkali-activated copper-nickel slag cementing material and a preparation method and application thereof, and relates to the technical field of solid waste utilization. The alkali-activated copper-nickel slag cementing material comprises solid powder and water, and the solid powder comprises the following components in percentage by mass: 50-65 wt% of copper-nickel slag powder, 28-45 wt% of an admixture and 5-15.2 wt% of a solid activator. The alkali-activated copper-nickel slag cementing material is prepared from the raw materials. The alkali-activated copper-nickel slag cementing material is prepared from solid powder composed of copper-nickel slag powder, an admixture and a solid activator according to a specific proportion and water, and the alkali-activated copper-nickel slag cementing material can realize use of the copper-nickel slag powder on a large scale, so that the problems of environmental pollution and farmland occupation caused by stacking or landfill of the existing copper-nickel slag powder are effectively relieved, and meanwhile, when the material is applied to mine filling, the mine filling cost can also be reduced, and good social and economic benefits are achieved.
本发明提供了一种碱激发铜镍渣胶凝材料及其制备方法和应用，涉及固废利用技术领域。所述碱激发铜镍渣胶凝材料包括固体粉料和水，其中：按质量百分数计，所述固体粉料包括以下组分：铜镍渣粉50～65wt％、掺合料28～45wt％和固体激发剂5～15.2wt％。由上述原料制备得到的碱激发铜镍渣胶凝材料，通过由铜镍渣粉、掺合料和固体激发剂按特定比例组成的固体粉料和水制得，上述碱激发铜镍渣胶凝材料可以将铜镍渣粉进行规模化利用，进而有效缓解了现有铜镍渣粉堆放或填埋造成的环境污染以及占用农田的问题；同时将其应用于矿井填充中，也能降低矿山充填的成本，具有较好的社会经济效益。
