Carbon sequestration cementing material system taking C2SF spinel as main component and preparation method of carbon sequestration cementing material system
The invention relates to a C2SF spinel-based carbon sequestration cementing material system and a preparation method thereof, and belongs to the field of solid waste resource utilization and carbon sequestration cementing materials. The carbon sequestration cementing material system is prepared from the following mineral phases in percentage by mass: 20 to 35 percent of C2SF, 20 to 30 percent of beta-C2S, 15 to 25 percent of C3S2, 10 to 20 percent of C4AF and 5 to 15 percent of CMS. According to the method, industrial solid wastes such as the steel slag, the fluorite tailings, the low-grade limestone and the ferrochrome slag are fully utilized to be fired into a carbon sequestration cementing material system taking C2SF spinel as a main component, the calcination temperature is 1150-1300 DEG C and is 150-200 DEG C lower than that of ordinary Portland cement clinker, energy consumption is reduced while part of industrial solid wastes are consumed, and the energy consumption is reduced. The material is an environment-friendly and sustainable building material; the industrial solid waste can be effectively utilized, and the problem of excessive accumulation of the industrial solid waste is solved.
本发明涉及一种以C2SF尖晶石为主的固碳胶凝材料体系及其制备方法，属于固废资源化利用和固碳胶凝材料领域。该固碳胶凝材料体系是由下述矿相组成质量分数为：20～35% C2SF、20～30% β‑C2S、15～25% C3S2、10～20% C4AF、5～15% CMS。本发明充分利用钢渣、萤石尾矿、低品位石灰石和铬铁渣等工业固体废弃物烧制成以C2SF尖晶石为主的固碳胶凝材料体系，煅烧温度为1150～1300℃，相较于普通硅酸盐水泥熟料的煅烧低150～200℃，消耗部分工业固体废弃物的同时减少能源消耗，是一种环保、可持续的建筑材料；且本发明可以有效利用工业固体废弃物，减轻工业固体废弃物堆积过多的难题。
