Reaction of gaseous atmospheric CO2 with calcium-bearing phases in concrete infrastructure components is known to cause a lowering of alkalinity, leading to depassivation and corrosion of rebars. Carbonation mechanism is quite well understood from a physico-chemical point of view, especially in the case of materials made of OPC. Nonetheless the impact of supplementary cementitious materials (SCM), such as fly-ash, on carbonation is still an active research field. The pozzolanic reaction between CH and fly ash implies a lower portlandite content and a higher C-S-H content. Whilst CH is buffering the pH, its lower content in these materials may lead to a lower resistance to carbonation and to a higher contribution of C-S-H in terms of microst...
