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, the value of the carbonation ratio by previous studies, we proposed a criteria for the carbonation suppression effect in consideration of the deterioration of the finishing material.

摘要

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, the value of the carbonation ratio by previous studies, we proposed a criteria for the carbonation suppression effect in consideration of the deterioration of the finishing material.
