Ground self-leveling mortar based on copper tailing waste residues and preparation method of ground self-leveling mortar
The invention provides ground self-leveling mortar based on copper tailing waste residues and a preparation method thereof, and the ground self-leveling mortar comprises the following components: 50 to 150 parts of 0 to 0.045 mm quartz stone powder, 50 to 150 parts of 0 to 0.075 mm copper tailing waste residue powder, 40 to 60 parts of 0.075 to 0.15 mm copper tailing waste residue, 150 to 200 parts of 0.15 to 0.3 mm copper tailing waste residue, 30 to 60 parts of 0.3 to 0.6 mm copper tailing waste residue, 180 to 220 parts of 0.3 to 0.6 mm quartz sand, 230 to 270 parts of P.O42.5 cement, 80 to 120 parts of sulphoaluminate cement and 20 to 40 parts of anhydrite. The concrete is prepared from the following components in parts by weight: 0.8-0.9 part of tartaric acid, 6-8 parts of redispersible latex powder, 0.6-0.8 part of cellulose ether, 0.8-1.0 part of a water reducing agent and 200-240 parts of water. According to the method, the residual tailing waste residues obtained after valuable minerals are recycled from the copper tailings are utilized, the copper tailing waste residues with different grain sizes can be blended to meet the use performance requirements of different ground self-leveling mortar, the process is simple, the production cost is low, all-component resource utilization of the copper tailing waste residues can be achieved, the application range is wide, consumption of natural gravel is reduced, and the production cost is reduced. High-added-value utilization of the copper tailing waste residue powder is achieved, the treatment problem of the copper tailing waste residues is effectively solved, and the environmental and economic benefits are remarkable.
本发明提供一种基于铜尾矿废渣的地面自流平砂浆及其制备方法，其组份为：0‑0.045mm石英石粉50‑150份，0‑0.075mm铜尾矿废渣粉50‑150份，0.075‑0.15mm铜尾矿废渣40‑60份，0.15‑0.3mm铜尾矿废渣150‑200份，0.3‑0.6mm铜尾矿废渣30‑60份，0.3‑0.6mm石英砂180‑220份，P·O42.5水泥230‑270份，硫铝酸盐水泥80‑120份，硬石膏20‑40份，酒石酸0.8‑0.9份，可再分散乳胶粉6‑8份，纤维素醚0.6‑0.8份，减水剂0.8‑1.0份，水200‑240份。本发明利用铜尾矿回收有价值矿物后的剩余尾矿废渣，可调配不同颗粒级配铜尾矿废渣以满足不同地面自流平砂浆使用性能要求，工艺简单、生产成本低、铜尾矿废渣可实现全组分资源化利用，适用范围广，减少了自然砂石的消耗，实现了对铜尾矿废渣粉料的高附加值利用，有效解决铜尾矿废渣的处理难题，环境和经济效益显著。
