Solid waste-based composite cementing material as well as preparation method and application thereof
The invention belongs to the technical field of solid waste resource utilization, and provides a solid waste-based composite cementing material and a preparation method and application thereof, and the solid waste-based composite cementing material is prepared from the following raw materials in parts by mass: 80-90 parts of composite cementing clinker and 10-20 parts of dihydrate gypsum. The raw materials selected by the invention are industrial solid wastes, so that the resource utilization of a large amount of industrial solid wastes is realized, a large amount of mineral resources are saved, and the cost of the raw materials is greatly reduced; the carbide slag, the desulfurized gypsum and the like have enough fineness and do not need to be ground again, so that the raw material grinding quantity can be greatly improved, the grinding power consumption is greatly reduced, the solid waste treatment cost of related enterprises is reduced, and the actual problems of environmental pollution, resource waste and the like caused by massive accumulation can be effectively avoided. According to the solid-waste-based composite cementing material provided by the invention, the highest 4h neat paste strength can reach 30.85 MPa, the highest 28d neat paste strength can reach 84.78 MPa, and the solid-waste-based composite cementing material has good working performance and mechanical performance.
本发明属于固体废物资源利用技术领域，提供了一种固废基复合胶凝材料及其制备方法和应用，由下列质量份数的原料制备得到：复合胶凝熟料80～90份，二水石膏10～20份。本发明选用的原料为工业固体废弃物，不但实现了大宗工业固废的资源利用，而且节约了大量矿产资源，使得生料成本大幅降低；电石渣、脱硫石膏等已具有足够的细度无需再次进行粉磨，因此生料磨出量可大幅提高，粉磨电耗大幅度降低，降低了相关企业的固废处理成本，能有效地避免大量堆积造成的环境污染、资源浪费等实际问题。本发明提供的固废基复合胶凝材料4h净浆强度最高达30.85MPa，28d最高可达84.78MPa，具有良好的工作性能和力学性能。
