Abstract: This paper presents the influence of recycled aggregates on air and water permeability of concrete. In the case of concrete with high water cement ratio, air and water permeability of concrete used recycled aggregate as a fine or a coarse aggregate become large in comparison those of concrete used river sand and crushed gravel. The results of air permeability test of concrete under compressive stress indicates that concrete used recycled
coarse aggregate has lower stress level at which air flow rate increases significantly due to load-induced microcracks than concrete used crashed gravel.
