Abstract
Various studies has been examined the effect of carbonation suppressive for concrete by coating materials.In order to evaluate the effect of carbonation suppressive for concrete of a large number of coating materials rapidly, it is desirable to develop a more simple and rapid method. In this paper was studied to quickly evaluate the effect of carbonation suppressive for concrete, by evaluate the carbon dioxide Permeability with a method of permeability cup and box. As a result, there was certain correlation between carbon dioxide permeability of coating materials by box method and carbonation rate of coating materials by accelerated carbonation of concrete.
