High-performance lightweight aggregate for lightweight ultra-high performance concrete and preparation method of high-performance lightweight aggregate
The invention provides a high-performance lightweight aggregate for lightweight ultrahigh-performance concrete and a preparation method of the high-performance lightweight aggregate. The aggregate comprises the following components in percentage by weight: 30-40% of copper tailing slag, 25-35% of lithium slag, 10-20% of red mud, 5-15% of pyrite cinder, 3-8% of titanium slag, 1-3% of calcium carbonate and 1-3% of magnesium carbonate. The invention further discloses a preparation method of the high-performance light aggregate for the light ultra-high-performance concrete, and the high-performance light aggregate is prepared from the industrial solid waste copper tailings, the lithium slag, the red mud, the pyrite cinder, the titanium slag, the calcium carbonate and the magnesium carbonate through the procedures of drying, uniform mixing, grinding, pelleting, aging, balling, high-temperature firing and the like. And when the material is applied to lightweight ultra-high performance concrete, the strength, the volume stability and the durability of the lightweight ultra-high performance concrete are improved, and meanwhile, the preparation cost of LUHPC is also reduced.
本发明提供了一种轻质超高性能混凝土用高性能轻集料及其制备方法，该集料包括按重量百分数计由如下组分组成：铜尾矿渣30‑40%、锂渣25‑35%、赤泥10‑20%、硫铁矿烧渣5‑15%、钛矿渣3‑8%、碳酸钙1‑3%、碳酸镁1‑3%。本发明还公开了一种轻质超高性能混凝土用高性能轻集料的制备方法，通过将工业固废铜尾矿渣、锂渣、赤泥、硫铁矿烧渣和钛矿渣与碳酸钙、碳酸镁经烘干、混匀、粉磨、造粒、陈腐、成球和高温烧制等工序制得高性能轻集料，并应用于轻质超高性能混凝土，提高其强度、体积稳定性和耐久性，同时也降低LUHPC的制备成本。
