Cement-based artificial stone containing copper tailings as well as preparation method and application thereof
The embodiment of the invention provides a copper-containing tailing tree cement artificial stone and a preparation method and application thereof, and the copper-containing tailing tree cement artificial stone comprises 50-60 wt% of quartz sand; 20 wt% to 35 wt% of cement; 3 wt% to 15 wt% of copper tailings; 2 wt%-5 wt% of silica fume; 0.1 wt% to 0.2 wt% of a water reducing agent; wherein the particle size of the copper tailings is greater than 200 meshes. According to the copper-tailing-containing cement-based artificial stone disclosed by the embodiment of the invention, the superfine copper tailings with more than 200 meshes are used as a cementing material-cement filling material of the cement-based artificial stone, and the superfine copper tailing powder is doped into the cement-based material of the artificial stone, so that the superfine copper tailing powder is better filled into the internal structure of cement, and the effect of consuming the copper tailings can be achieved; the environment pressure caused by tailing stockpiling is relieved, and it can be guaranteed that the strength of the prepared copper-containing tailing cement-based artificial stone reaches the corresponding standard at low cost.
本公开实施例提供一种含铜尾矿树水泥人造石及其制备方法和应用，本公开实施例的含铜尾矿水泥基人造石，包括50wt％～60wt％的石英砂；20wt％～35wt％的水泥；3wt％～15wt％的铜尾矿；2wt％～5wt％的硅灰；0.1wt％～0.2wt％的减水剂；其中，铜尾矿的粒径大于200目。本公开实施例的含铜尾矿水泥基人造石，采用200目以上的极细铜尾矿，作为水泥基人造石的胶凝材料—水泥的填充材料，用极细的铜尾矿粉掺入人造石的水泥基材料中，令它更好的填充到水泥的内部结构中，不仅可以起到消耗铜尾矿的作用，减轻尾矿堆存带来的环境压力，还可以以较低的成本保证制备的含铜尾矿水泥基人造石的强度达到相应的标准。
