Rapid Evaluation Methods of coating Materials for Controlling Performance Carbonation Suppressive for Concrete

Part2 Effect of Reagent Amount and Humidity Condition

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 evaluate the carbon dioxide Permeability of coating materials with a method of permeability box. In addition, we confirm the amount of reagent effects and humidity conditions to give carbon dioxide permeability. As a result, it was found that the permeability of carbon dioxide can be evaluated quantitatively by the box method.
