Effect of natural and accelerated carbonation on microstructure and pH of sodium carbonate alkali-activated slag

This study aims to understand the effect of the natural and accelerated carbonation on the alkali-activated slag (AAS) activated by sodium carbonate. Carbonation increased AAS paste total porosity but reduced slag containing materials (CEM III) porosity. The pH after carbonation was higher in AAS th...
