Conclusions

Based on a comprehensive understanding of the reaction mechanism of alkali-activated industrial solid waste cementitious materials, this study developed alkali-activated electrolytic manganese residue (EMR)-based grouting slurries with different material formulations. Focusing on laboratory tests, investigations were conducted into the performance activation of EMR, the engineering and environmental properties of EMR-based grouting materials, as well as the effects of admixtures on such materials. The technical feasibility of alkali-activated industrial solid waste-based grouting materials and the superior performance of the prepared slurries were verified. In addition, the industrial solid waste-based slurries were tested and analyzed in this study, aiming to lay a solid theoretical foundation for their future engineering applications.
