Enhancing the interfacial transition zone of coal gangue aggregate mortar through the synergistic effect of red mud substitution and CO₂ mineralization during mixing

To improve the weak interfacial transition zone (ITZ) associated with coal gangue (CG) aggregates while promoting industrial solid waste valorization and carbon reduction, a synergistic modification strategy combining red mud (RM) substitution (8–24%) and in-situ CO₂ mineralizati...
