Application of superfine tailings in concrete
The invention discloses application of superfine tailings in concrete, and belongs to the technical field of tailing treatment. The concrete is prepared from the following components in parts by mass:13-19 parts of a cementing material, 0-4 parts of superfine tailings, 33.5-35 parts of fine aggregate, 41-42.5 parts of stones, 5-7 parts of water and 0.2 part of a water reducing agent. According tothe invention, the superfine tailings are particularly used as concrete admixtures to replace cementing materials and water, so that the resource utilization of the superfine tailings is realized, and an effective way is provided for the comprehensive treatment of national tailings ponds. According to the concrete, the dosage of a cementing material and carbon emission are remarkably reduced, more importantly, the economic value of tailings can be greatly improved while the strength of the concrete is improved, and the concrete has a wide application prospect.
本发明公开一种超细尾砂在混凝土中的应用，属尾砂处理技术领域。该混凝土按质量份数计，包括13‑19重量份的胶凝材料、0‑4重量份的超细尾砂、33.5‑35重量份的细骨料、41‑42.5重量份的石子、5‑7重量份的水和0.2重量份的减水剂。本发明特别采用了超细尾砂用作混凝土掺合料替代胶凝材料和水，实现了超细尾砂资源化利用，为全国尾矿库综合治理提供了一种有效途径。通过本发明生产的混凝土不仅显著降低了胶凝材料的用量和碳排放，更重要的是在提升混凝土强度的同时还可以大幅提高尾砂的经济价值，具有广阔的应用前景。
