✦ Synopsis

The effects of sulfate and CO1 on chloride penetration fronts and diffisivities were determined at 60 months exposure for ordinary Portland cement concrete and concrete incorporating the partial replacement of the cement with slag. It was found that sulfate and CO2 decrease the chloride penetration and diffisivity in the ordinary Portland cement concrete whereas the opposite behavior is observed for the slag concrete. However, chloride ingress is always considerably less in the slag concrete.
