Air permeability of structural concrete is one of the properties of concrete in the surface layer concrete. It is strongly relative with the rate of carbonation. For this reason, air permeability test is effective with respect to the evaluation for the durability of structural concrete. Having intended to measure air permeability of structural concrete in site, the authors have handled rapid air permeability test which is based on J. W. Figg's concept. This paper proposes "rapid test method for air permeability of structural concrete with drilled-hole" which is considered to apply for structural concrete. The method is also specified according to the knowledge of examination for the factor on air permeability. The paper moreover presents the tendency which test results indicate on each factor of affecting the rapid air permeability test.
