Abstract: GUIMARÃES [1] have shown that the application of deterministic models based only on the Fick's Laws can exhibit considerable differences to the effective chloride profiles in existing marine structures. In this research, a laboratory test method to estimate the influence of the concrete saturation degree (SD) on chloride diffusion was developed. Test results were applied to an existing 22 years old marine structure. Results indicate that the concrete SD has a great influence on chloride diffusion and requires further research. Therefore, this factor should be taken into account when estimating the service life of concrete structures.
