High-performance concrete slabs have been field exposed at the Traslovslage marine field station at the Swedish west coast since April 1992 as a part of the Cementa/Euroc sponsored project, "Durability of Marine Concrete Structures". The concrete slabs mounted on a floating pontoon are exposed in 3 exposure zones, i.e., submerged-, splash- and upper splash zones. The results after 2 years of exposure confirmed the expected inverse relationship between chloride ingress and water to binder ratio. The use of 5-10 percent silica fume in the binder had a very positive effect on reducing the chloride ingress, but no benefit at all was found for concrete with fly ash in the binder as compared to the use of 5 percent silica fume. Generally, the results indicated that high-performance concrete may be regarded as extremely resistant to degradation by reinforcement corrosion, as long as effects of cracks are not considered.
