文摘
- •
Dry and aqueous flue gas mineral carbonation routes were investigated.
- •
Two types of calcium-bearing residues were tested.
- •
Dry phase experiments did not showed any carbonates formation.
- •
Waste concrete is more reactive than anorthosite residues.
- •
34.6% of CO2 was converted into carbonate with concrete samples in aqueous phase.
