To promote the resource utilization of industrial solid waste and the sustainable development of green wet-mix shotcrete, cement clinker-free solid-waste-based wet-mix shotcrete was prepared using steel slag, slag, and desulfurization gypsum as cementitious materials, and copper slag and waste rock as aggregates. Furthermore, raw material property analysis, mix proportion optimization, mechanical property testing, microscopic mechanism investigation, and on-site industrial tests were systematically conducted. The results indicate that the mechanical properties of the solid-waste-based wet-mix shotcrete with optimal mix proportions (specimens No.5 and No.9) are superior to those of the cement-based wet-mix shotcrete. The 7-day compressive strength of specimen No.9 reaches 16.31 MPa, and its 56-day compressive strength exceeds 28 MPa. Its workability is comparable to that of the cement-based wet-mix shotcrete, and the slump and slump flow meet the requirements of wet spraying operations. The solid-waste-based wet-mix shotcrete exhibits a remarkable solidification effect on heavy metals. It reduces the leaching concentrations of excessive heavy metals Pb and Cd in the copper slag to below the Class Ⅱ water quality standard for groundwater, demonstrating excellent environmental safety. Microscopic analysis results indicate that the solid-waste-based wet-mix shotcrete is rich in hydration products and exhibits a high degree of polymerization of the silicate gel. On-site tests verify the feasibility of engineering application for the copper slag wet-mix shotcrete. Although issues such as incomplete material discharge exist, they can be improved through process optimization. This provides an effective path for the harmless disposal and resource utilization of solid wastes such as copper slag, possessing environmental, economic, and social values.

为推动工业固废资源化利用及绿色湿喷混凝土可持续发展，以钢渣、矿渣、脱硫石膏为胶凝材料，以铜渣、废石等为骨料，制备无水泥熟料固废基湿喷混凝土，系统开展了原料性质分析、配比优化、力学性能测试、微观机理探究及现场工业试验。结果表明：最优配比（5号、9号样品）的固废基湿喷混凝土力学性能优于水泥基湿喷混凝土，9号试样7 d抗压强度达到16.31 MPa，56 d抗压强度超过28 MPa，工作性能与水泥基湿喷混凝土相当，坍落度及扩展度符合湿喷作业需求。固废基湿喷混凝土对重金属固化效果显著，可将铜渣中超标的重金属Pb、Cd浸出浓度降至地下水Ⅱ类水质标准以下，表现出优异的环境安全性。微观分析结果表明，固废基湿喷混凝土水化产物丰富、硅酸盐凝胶聚合度高。现场试验验证了铜渣湿喷混凝土的工程应用可行性，虽存在下料不完全等问题，但可通过工艺优化改善，为铜渣等固废无害化处置与资源化利用提供了有效路径，兼具环境、经济与社会价值。
