Abstract

Permeability of cover concrete strongly affects the durability of reinforced concrete structures. This paper deals with a single-chamber vacuum cell for the evaluation of the cover concrete air-permeability. The original types have been developed by Schönlin and Hilsdorf in 1987 and by Berissi et al. also in 1987, respectively. Applicability of the method to concretes in Japan was examined through the comparisons between air-permeability coefficients (A.P.C.) defined in this method and accelerated carbonation depths of concretes with various water cement ratios. The correlation was quite good. The method successfully evaluated the air-permeability of full-sized concrete walls.
