Abstract
Influence of carbon dioxide permeability and moisture permeability of coating materials on carbonation depth of substrate concrete was discussed by 2 series of accelerated carbonation tests. Moisture permeability shows higher correlation than carbon dioxide permeability. Accordingly, moisture change in concrete was monitored in accelerated carbonation test in this study. It was found that water generated by carbonation reaction of concrete raise moisture content of the substrate concrete. Consequently, this increase of moisture content strongly affects the carbonation depths of concrete. In conclusion, moisture permeability has high correlation between carbonation depth, and which is due to generation of water by carbonation reaction in the accelerated carbonation test.
