Multi-element solid waste cementing material as well as preparation method and application thereof
The invention relates to the technical field of comprehensive utilization of solid waste materials, in particular to a multi-element solid waste cementing material as well as a preparation method and application thereof. The basic solid waste cementing material comprises the following raw materials in parts by weight: 23-25 parts of fly ash, 10-12 parts of carbide slag, 5-9 parts of desulfurized gypsum, 10-20 parts of steel slag, 12-14 parts of mineral slag and 25-30 parts of cement, and the average particle size of the used raw materials is 8-10 microns; the characteristics of various solid wastes are fully exerted through three main procedures of drying, grinding and uniform mixing, and the cementing material with good physical and mechanical properties is prepared by utilizing the synergistic enhancement effect of the solid wastes. The prepared multi-element solid waste gel can be applied to road base stabilization, road performance indexes such as unconfined compressive strength, scouring resistance, temperature shrinkage and dry shrinkage all meet the technical requirements of road pavement base construction, preparation of a green low-carbon gel material can be achieved, solid waste resource utilization can also be achieved, and the cost is reduced. The purposes of saving resources, protecting the environment and improving the road quality are achieved.
本发明涉及固废材料综合利用技术领域，特别是涉及一种多元固废胶凝材料及其制备方法和应用；元固废胶凝材料包括如下重量份配比的原料：粉煤灰23‑25份，电石渣10‑12份，脱硫石膏5‑9份，钢渣10‑20份，矿渣12‑14份、水泥25‑30份，所用原料的平均粒径均为8‑10微米；通过烘干、粉磨、混匀等三段主要工序充分发挥各种固废特性，利用其协同增强作用，制备出物理力学性能良好的的胶凝材料。本发明制备的多元固废胶凝可应用于道路基层稳定中，无侧限抗压强度、抗冲刷、温缩和干缩等路用性能指标均符合公路路面基层施工技术要求，既可实现绿色低碳胶凝材料的制备，亦可实现固废资源化利用，达到节约资源、保护环境、提高公路质量的目的。
