Preparation method of coal gasification slag-lithium slag-steel slag based lightweight concrete
The invention belongs to the technical field of comprehensive utilization of resources, and particularly relates to a preparation method of coal gasification slag-lithium slag-steel slag based lightweight concrete. According to the high-performance light-weight waste-utilizing concrete prepared from all solid wastes, the solid wastes used in the preparation comprise cyanidation tailings, steel slag, coal gasification ash, lithium slag, alkaline slag, silicon-calcium slag, phosphogypsum, stainless steel slag, sea sand, waste aerated concrete, barren rock, bagasse and the like, and the solid wastes have the advantages that the physical property, the working property and the mechanical property are excellent; according to the present invention, the index requirements in the lightweight aggregate concrete application technology standard JGJ/T 12-2019 are improved, the radioactivity meets the test index requirements in the Limit of Radionuclides in Building Materials GB 6566-2010, the safety meets the requirements of the Groundwater Quality Standard GB/T 14848-2017, the utilization rate of the solid waste raw material is improved, the production cost of the enterprise can be significantly reduced, and the economic benefit is significant. And economic benefits and social and environmental benefits are remarkable.
本发明属于资源综合利用技术领域，尤其涉及一种煤气化渣‑锂渣‑钢渣基轻质混凝土的制备方法。本发明利用全固废制备的高性能轻质利废混凝土，制备中使用的固体废弃物包括：氰化尾渣、钢渣、煤气化灰渣、锂渣、碱渣、硅钙渣、磷石膏、不锈钢渣、海砂、废弃加气混凝土、废石、甘蔗渣等，其在物理性能、工作性能、力学性能方面，较《轻骨料混凝土应用技术标准》JGJ/T 12‑2019中指标要求都有所提升，其放射性符合《建筑材料放射性核素限量》GB 6566‑2010中测试指标要求，同时安全性满足《地下水质量标准》GB/T 14848‑2017的要求，本发明提高了固废原料的利用率，可显著降低企业的生产成本，经济效益及社会环境效益显著。
