Abstract

Various studies have been conducted to estimate the suppressive effects of coating materials on the carbonation of concrete. For many coating materials, a simpler and faster evaluation method than the accelerated carbonation test and the air permeability test is necessary. We applied a box method to evaluate the carbon dioxide permeability of coating materials and determined that the permeability could be evaluated quantitatively. In addition, the evaluation was completed within one or two weeks. Hence, the box method can evaluate carbon dioxide permeability rapidly and is useful for predicting the suppressive effect of coating materials on the carbonation of concrete.
