- •
Carbonation potential of MgO and PC concrete mixes were studied at different depths.
- •
Mix performances were assessed by their strength, density, porosity and CO2 uptake.
- •
MgO mixes achieved higher carbonation degrees and strengths than PC mixes.
- •
Dense networks of various carbonates were observed at different sample depths.
- •
Providing a continuous path for CO2 diffusion through careful mix design is vital.
