Copper tailing powder-based composite mineral admixture and preparation method thereof
The invention discloses a copper tailing powder-based composite mineral admixture which comprises the following components in parts by weight: 57-120 parts of composite micro powder, 3-8 parts of slaked lime and 1-5 parts of sodium sulfate, the composite micro powder is obtained by mixing and calcining modified copper tailing powder, fly ash, mineral powder and silica fume as main raw materials. The modified copper tailing powder is prepared by carrying out vacuum blending modification on copper tailing powder by adopting MV-10 (Mn). The modified copper tailing powder, the fly ash, the mineral powder and the silica fume are used as main raw materials, efficient resource utilization of various low-quality industrial solid wastes can be achieved, and good economic and environmental benefits are achieved; the obtained copper tailing powder-based composite mineral admixture can effectively shorten the setting time of concrete, can further improve the working properties (fluidity, cohesiveness, water retention and the like), mechanical properties, long-term durability and the like of the obtained concrete, and is suitable for popularization and application.
本发明公开了一种铜尾矿粉基复合矿物掺合料，各组分及其所占重量份数包括：复合微粉57～120份，熟石灰3～8份，硫酸钠1～5份；所述复合微粉以改性铜尾矿粉、粉煤灰、矿粉和微硅粉为主要原料进行混合、煅烧得到；所述改性铜尾矿粉采用MUV‑10(Mn)对铜尾矿粉进行真空共混改性而成。本发明以改性铜尾矿粉、粉煤灰、矿粉、微硅粉为主要原料，可实现多种低品质工业固废的高效资源化利用，具有良好的经济和环境效益；所得铜尾矿粉基复合矿物掺合料可有效缩短混凝土的凝结时间，同时可进一步改善所得混凝土的工作性能(流动性、粘聚性和保水性等)、力学性能、长期耐久性能等，适合推广应用。
