Overview

• Researchers used innovative methods such as 29Si NMR and 1H NMR relaxometry to investigate carbonation.
• Findings show that the carbonation process is influenced by relative humidity and calcium/silicate ratios.
• Structural changes during carbonation impact the efficiency of CO2 absorption in cement-based materials.
• Accelerated carbonation experiments provide insights that can lead to new CO2-absorbing building materials.
• Study contributes to understanding carbonation in both man-made and natural compounds.
