Preparation method and application of silver tailing composite material
The invention discloses a preparation method and application of a silver tailing slag composite material, and the preparation method comprises the following steps: drying and carbonizing silver tailing slag, mixing the carbonized silver tailing slag with iron-ore slag powder and fly ash, adding a YT auxiliary agent and a YTM auxiliary agent, and grinding; after the cement modifier is applied to cement, the early-stage strength of the cement is basically kept unchanged, the later-stage strength is slightly increased, and other indexes also meet the quality index requirements. Due to the doping of fine particles, the durability, the anti-freezing property and the anti-permeability of the cement are all improved. The test shows that the composite admixture can be recycled in cement production.
本发明公开了一种银尾矿渣复合材料的制备方法及应用，该制备方法通过将银尾矿渣烘干、碳化后，与铁矿渣粉、粉煤灰混合，加入YT助剂和YTM助剂后进行研磨；应用于水泥后，水泥的前期强度基本保持不变，后期强度还少有增长，其它的指标也符合质量指标要求。因掺入微细颗粒，水泥的耐久性、防冻性、抗渗性都会有所提高。通过上述试验表明，这种复合掺加料可以在水泥生产中得到资源化应用。
