Abstract: In order to provide more information about the effect of various supplementary cementing materials on the resistance of concrete against chloride penetration, an experimental program was carried out. The results showed that the various replacement materials significantly increased the resistance of the concrete against chloride penetration compared to that of the reference concrete based on pure portland cement. For a given water/binder ratio, the resistance of the concrete varied within wide limits depending on the type of binder system. For a given concrete structure in a given marine environment, calculations of the corrosion probability showed that the various binder systems would give very different service periods before a 10 % probability of corrosion would be reached. Such a comparison of the various concrete mixtures appears to provide a proper basis for durability design of new concrete structures in severe environments.
