Preparation method of alkali-activated copper slag-based pervious concrete and alkali-activated copper slag-based pervious concrete
The invention provides a preparation method of alkali-activated copper slag-based pervious concrete and the alkali-activated copper slag-based pervious concrete. The method comprises the following steps: (1) respectively carrying out dry grinding on copper slag and carbide slag to obtain copper slag powder and carbide slag powder; crushing the red mud, and performing dry grinding to obtain red mud powder; (2) 195-205 parts by weight of copper slag powder and 95-105 parts by weight of water are taken, 0.1-0.2 part by weight of a water reducing agent is added, wet grinding is conducted for 15-25 min, and copper slag slurry is obtained and marked as slurry A; taking 80-83 parts by weight of red mud powder and 160-165 parts by weight of water, and performing wet grinding for 20-40 minutes to obtain red mud slurry which is marked as slurry B; (3) mixing ammonium tartrate, sodium sulfate, lignosulfonate, hydroxypropyl methyl cellulose and wood fiber according to a ratio of 1: 2: 3: 1: 1 to prepare a reinforcing agent; and (4) uniformly stirring 20-40 parts by weight of carbide slag powder, 50-60 parts by weight of the slurry A, 30-40 parts by weight of the slurry B, 2-8 parts by weight of sodium carbonate, 5-15 parts by weight of water, 2-3 parts by weight of a reinforcing agent, 1-2 parts by weight of a water reducing agent, 120-160 parts by weight of river sand, 40-80 parts by weight of copper slag powder and 250-350 parts by weight of coal gangue.
本发明提供一种碱激发铜渣基透水混凝土的制备方法以及碱激发铜渣基透水混凝土。该方法包括：(1)分别将铜渣、电石渣干磨，得到铜渣粉、电石渣粉；将赤泥破碎，再干磨，得到赤泥粉；(2)取195‑205重量份铜渣粉、95‑105重量份水，加入0.1‑0.2重量份减水剂，湿磨15‑25min，得到铜渣浆料，记作浆料A；取80‑83重量份赤泥粉，160‑165重量份水，湿磨20‑40min，得到赤泥浆料，记作浆料B；(3)将酒石酸铵、硫酸钠、木质磺酸盐、羟丙基甲基纤维素以及木质纤维按照1:2:3:1:1的比例混合，制备增强剂；(4)分别取电石渣粉20‑40重量份、A浆料50‑60重量份和B浆料30‑40重量份、碳酸钠2‑8重量份、水5‑15重量份、增强剂2‑3重量份、减水剂1‑2重量份、河沙120‑160重量份和铜渣粉40‑80重量份、煤矸石250‑350重量份，搅拌均匀。
