All-solid waste cementing material containing lithium slag and preparation method of all-solid waste cementing material
The invention relates to an all-solid waste cementing material containing lithium slag and a preparation method of the all-solid waste cementing material. The all-solid waste cementing material is prepared from mineral slag, lithium slag, steel slag, carbide slag and ardealite in a mass ratio of (20-40): (20-30): (20-25): (5-10): (10-20). The preparation method comprises the following steps: preliminarily crushing, screening, drying and grinding the raw materials including the slag, the steel slag, the carbide slag and the ardealite; calcining the lithium slag at a high temperature of 700-900 DEG C for 2 hours, activating, and grinding; and respectively weighing the ground components in proportion, and uniformly stirring to obtain the all-solid waste cementing material. The all-solid waste cementing material disclosed by the invention is free of cement clinker, free of any additives such as an alkaline activator and a water reducing agent, high in later strength and good in volume stability. The all-solid-waste cementing material can replace cement to be applied to a road base, the road performance is met, meanwhile, solid waste such as steel slag, lithium slag and ardealite with the low comprehensive utilization rate is consumed, and the all-solid-waste cementing material has the advantages of being high in solid waste utilization rate, capable of saving energy, environmentally friendly, good in social benefit, wide in application prospect and the like.
本发明涉及一种含锂渣的全固废胶凝材料及其制备方法，全固废胶凝材料组成及质量比为矿渣：锂渣：钢渣：电石渣：磷石膏＝20～40：20～30：20～25：5～10：10～20。制备方法为：将原料矿渣、钢渣、电石渣与磷石膏进行初步破碎筛分并烘干粉磨；将锂渣在700～900℃温度下高温煅烧2h进行活化处理后再进行粉磨；按比例分别称取研磨后的各组分，搅拌均匀制得全固废胶凝材料。本发明的全固废胶凝材料无水泥熟料且不添加任何外加剂如碱性激发剂、减水剂等，后期强度高、体积稳定性好。本发明的全固废胶凝材料可代替水泥应用于公路基层中，满足路用性能的同时消纳钢渣、锂渣、磷石膏等综合利用率低的固废物，具有固废利用率高、节能环保、社会效益好以及应用前景广阔等优势。
