Coupled influence of acidic impurities in incineration flue gas on CO2 mineralization and phase composition of steel slag-based aggregates

Puntos clave

• CO2 mineralization is significantly affected by acidic impurities in flue gas, enhancing aggregate quality.
• A crucial finding is that acidic impurities promote specific changes in the phase composition of steel slag-based aggregates.
• Observational analysis focused on the interaction between flue gas impurities and steel slag during incineration processes.
• These findings may enable better utilization of steel slag aggregates in construction, reducing carbon emissions.
