Implication

Demonstrates that lime–biochar modification enhances carbon sequestration and strength in alkali-activated slag, indicating a path towards low-carbon construction materials.

Key Points

  • The aim is to investigate the effects of biochar and lime on the strength and carbon capture of CO2-cured alkali-activated slag.
  • Experimental design focused on incorporating lime and biochar into alkali-activated slag pastes.
  • Evaluation of compressive strength after 28 days of curing.
  • Characterization of microstructure and pore structure using hydration product analysis.
  • Achieved a compressive strength of 60.97 MPa after 28 days with lime–biochar modification.
  • Strength increased by 11.4% compared to the control mixture.
  • Optimized biochar inclusion enhanced CO2 uptake by achieving up to 86.8 kg of CO2 per ton of binder.
