Abstract
Three ordinary Portland cement concrete piers were exposed in the North Sea, Scotland region for a period of 7 years. Concrete dust samples were taken at regular intervals of exposure to obtain chloride profiles. Apparent diffusion coefficient and surface chloride concentration were calculated using the chloride profiles. The exposure can be classified in four different regimes, namely, the submerged, the splash, the tidal and the atmospheric zone. Variation of diffusion coefficients and surface chloride concentrations with exposure criteria are discussed in this paper.
