Low-carbon environment-friendly solid waste filling material for mine filling and preparation method of low-carbon environment-friendly solid waste filling material
The invention relates to the technical field of building materials, in particular to a low-carbon environment-friendly solid waste filling material for mine filling and a preparation method thereof.The low-carbon environment-friendly solid waste filling material for mine filling is prepared from, by mass, 2-15% of cementing materials, 0-5% of fly ash and 0-90% of tailing sand, the cementing material is prepared from 1 to 3 weight percent of high calcium oxide-belite cementing material, 2 to 5 weight percent of sulphoaluminate cement clinker, 70 to 80 weight percent of slag and 15 to 25 weight percent of anhydrite. The low-carbon environment-friendly solid waste filling material for mine filling is obtained through the synergistic effect of the cement clinker, the slag, the anhydrite, the fly ash and the tailing sand, the setting and hardening speed is high, the strength meets the requirement of a filling body, the usage amount of the cement clinker is small, the usage proportion of solid waste is large, and the comprehensive cost is low.
本发明建筑材料涉及技术领域，具体涉及一种矿山充填用低碳环保的固废充填材料及其制备方法，所述矿山充填用低碳环保的固废充填材料包括质量百分计的2～15wt.％胶凝材料、0～5wt.％粉煤灰、0～90wt.％尾矿砂，所述胶凝材料包括1～3wt.％高氧化钙‑贝利特胶凝材料、2～5wt.％硫铝酸盐水泥熟料、70～80wt.％矿渣、15～25wt.％硬石膏。本发明利用水泥熟料、矿渣、硬石膏、粉煤灰、尾矿砂协同作用，得到矿山充填用低碳环保的固废充填材料，凝结硬化速率快，强度满足充填体要求，且水泥熟料使用量少，固废使用比例大，综合成本低。
