In this study, the Rapid Air permeability test apparatus applicable to a concrete structure was developed and various factors which have on air permeability index were examined. As a result, the test condition which secures experimental flexibility and reproducibility was clarified. Moreover, a possibility that air permeability index could apply as an evaluation index of scaling resistance was shown, by investigating the relation between Air permeability indexes and scaling resistance.
