Roadbed material containing multi-source solid waste and construction method
The invention relates to the technical field of roadbed construction, in particular to a roadbed material containing multi-source solid waste and a construction method.The roadbed material containing the multi-source solid waste is prepared from, by mass, 30%-40% of red mud, 0-9% of iron tailings, 0-10% of fly ash, 0-5% of alkaline residues, 0-8% of lime, 20%-30% of solid waste-based cementing materials and 20%-30% of sandy soil; the solid waste-based cementing material is composed of slag, steel slag and desulfurized gypsum, and the mass ratio of the slag to the steel slag to the desulfurized gypsum is 3: 2: 1.5; according to the invention, a plurality of solid wastes are used as roadbed materials, and the solid wastes can be recycled, so that the utilization of materials such as cement, lime and the like is reduced, the pollution to the environment is reduced, and the production cost is saved.
本发明涉及路基施工技术领域，具体是一种含有多源固废的路基材料及施工方法，含有多源固废的路基材料，由下列质量百分比物质构成：赤泥30%~40%、铁尾矿0~9%、粉煤灰0~10%、碱渣0~5%、石灰0~8%、固废基胶凝材料20%~30%、砂土20%~30%；固废基胶凝材料由矿渣、钢渣、脱硫石膏构成，矿渣、钢渣、脱硫石膏的质量比为3:2:1.5；本发明通过使用多种固体废弃物作为路基材料，能够实现固体废弃物的回收利用，从而减少了水泥和石灰等材料的利用，减少了对环境的污染，节约了生产成本。
