Abstract
VOC in the paint is spread and penetrated in surface of painted concrete. So, it is possible to considered that carbonation is inhibited because VOC is intervening around moisture in concrete. Further carbonation is suppressed by effectiveness of bloking transmission of carbon dioxide of coating.There we verified the effectiveness of VOC and the effectiveness carbon dioxide permeability by experiment with each factor. As a result, we show that VOC which is richly water-insoluble compound remain in the surface of painted concrete and VOC has transient carbonation suppressive effects until it is dried and vanished. Therefore we show it is appropriate to evaluate carbonation suppressive with coatings based on method of accelerated carbonation test data for late, that is not affected in VOC and is from that point showed progression of carbonation is faster because VOC is dry and vanished.Further we show that carbon dioxide gas-transmission rate of coatings has a very high correlation with carbonation suppressive of coating materials for textured finishes of buildings and liquid-applied compounds for waterproofing membrane coating of buildings.So it is possible to evaluate carbonation suppressive by measuring of coatings.
