The permeability coefficient is a characteristic of concrete which indicates the rate of fluid transport through concrete. It is well-known that the decrease of permeability is the key factor of concrete durability. In this paper, the oxygen permeability of concrete based on Cembureau method has been studied. In addition, the results obtained for oxygen permeability coefficient were compared with those obtained for water permeability and electrical resistance experiments to perform a better investigation. For this purpose, 4 concrete mixtures were made. The mixtures included a control mixture and 3 silica fume incorporated mixtures with replacement levels of 5%, 10% and 12.5%. The water to cementitious materials ratio and the cementitious materials content were kept constant at 0.4 and 400 kg/m3, respectively. Comparing the test result of the mixtures showed that silica fume improves the characteristics of concrete durability and also the results of gas permeability have a proper compatibility with those of water permeability.
