“…Since then, several researchers have demonstrated the advantages of treating either wet or hardened cement paste with scCO 2 to produce fully carbonated cement matrices, either as monoliths or reinforced with glass fibres with improved mechanical and chemical properties. A wide range of cementitious materials can be rapidly carbonated to almost uniform carbonate content throughout the depth of the treated samples with a resultant matrix having an almost neutral pH [6,7,8,10,11,14,15,22,23].…”
