Superfine copper tailing-based cement-free concrete
The invention discloses a superfine copper tailing based cement-free concrete and a preparation method thereof. The invention relates to a high-strength and high-strength concrete which is composed of the following raw materials: 6-10 parts of a nano rare earth binder, 3-7 parts of quasi-nano superfine copper tailings with the specific surface area of 500-1200 square meters/kg, 6-10 parts of quasi-nano silica-alumina gel powder with the specific surface area of 500-1200 square meters/kg, 20-30 parts of 20-600-mesh continuous grading copper tailings, 45-55 parts of 3-30 mm continuous grading copper tailings barren rock, 0.2-0.5 part of a polycarboxylic acid water reducer and 2-4 parts of a reinforcing agent. The invention relates to the field of engineering material concrete. The superfine copper tailing-based cement-free concrete solves the problems that the existing cement concrete is low in bonding performance with steel bars, poor in freeze-thaw resistance and chemical erosion resistance, low in density, high in cost and not environment-friendly enough.
本发明公开了一种超细铜尾矿基无水泥混凝土，其特征在于，以重量份数计，由以下原料组成：6‑10份纳米稀土粘结剂、3‑7份比表面积500‑1200平米/公斤的准纳米超细铜尾矿、6‑10份比表面积500‑1200平米/公斤的准纳米硅铝胶粉、20‑30份20‑600目的连续级配铜尾矿、45‑55份3mm‑30mm的连续级配铜尾矿废石、0.2‑0.5份聚羧酸减水剂、2‑4份增强剂。本发明涉及工程材料混凝土领域。该超细铜尾矿基无水泥混凝土解决了现有的水泥混凝土与钢筋粘结性能低、抗冻融性和抗化学侵蚀能力差、致密度低、成本高、不够环保的问题。
