STUDY ON EVALUATION METHOD AND CRITERIA FOR CARBONATION SUPPRESSION EFFECT OF EXTERIOR FINISHING MATERIALS

In this study, we examined the evaluation method and evaluation criteria for evaluating the carbonation suppression effect of finishing materials used for the exterior of reinforced concrete buildings. We proposed a test method for carbon dioxide transmission rate of finishing materials and clarified the relationship with the carbonation ratio by the accelerated carbonation test while 52 weeks. In addition, based on the carbon dioxide transmission rate after the accelerated weathering test and the value of the carbonation ratio by previous studies, we proposed an evaluation criteria for the carbonation suppression effect in consideration of the deterioration of the finishing material.
