Concrete specimens with various binders including Portland cement, fly ash, blast furnace slag and composite cement and three water-to-cement ratios were subjected to cyclic wetting with salt solution and drying. After salt loading for half a year, chloride profiles were determined. Subsequently, chloride loading was discontinued and specimens were exposed for two years in various climates (20°C 80%RH, outside, fog room). The chloride distribution was measured at the end of the exposure period. Concrete resistivities were measured using embedded electrodes.
