ABSTRACT
Air permeability of structural concrete is one of important properties of near-surface 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 developed rapid air permeability test based on Figg’s concept. This paper proposes “rapid test method for air permeability of structural concrete with drilled-hole” which is intended to apply for structural concretes. The method is also specified according to the knowledge of examination for the factor on air permeability. This paper also show the tendency which test results indicate on each factor affecting the rapid air permeability test.
