Abstract:
The energy consumption and carbon emissions in the construction field, coupled with the accumulation of various industrial solid wastes, particularly bauxite residue (red mud), represent formidable barriers to sustainable development. The synergistic utilization of bauxite residue (red mud) in cementitious materials and special concrete is widely considered one of the most practical approaches for these issues. In this comprehensive review, characteristics and composition of red mud worldwide were investigated. By comparing and reviewing the latest research, the current achievements in applying red mud with various solid wastes in cementitious materials and special concrete were discussed. In addition, critical mechanisms and environmental suitability issues are emphasized. In conclusion, the present work culminates in identifying the challenges faced and opportunities for progressing in synergizing red mud and multi-solid wastes, which will contribute to the international research community for sustainable development in the industry.
