Abstract:In the current work, an extensive chloride-profiling programme was taken over a seven year period on a series of nine concrete monoliths placed at a marine location. These monoliths were 2.0m high and octagonal in plan with each vertical face 0.66m wide. The monoliths were placed at predefined locations to represent environmental exposure conditions of XS1 (exposed to airborne salt and not in direct contact with sea water) and XS3 (tidal, splash and spray zones) as defined with European Standard EN206-1. The concrete monoliths were constructed in groups of three (one each at the locations defined above): one group, which was used as a benchmark, represented normal portland cement concrete; the second group of monoliths was treated with waterproofing agent (caltite) added at the time off mixing and the third was treated with silane. Chloride profiles were taken at a number of positions on each monolith which were subsequently used to evaluate the performance of the concrete to chloride ingress for different exposure conditions.
