    This work documents the effect of different temperature levels on chloride penetration through a saturated CEM-I mortar. The temperatures studied were 5, 21 and 35°C. In addition to experiments, a model based on multi-ionic diffusion is proposed. It is highlighted that the temperature level has no impact on the chloride binding during immersion tests in NaCl solution, for marine environment concentrations. The chloride diffusivity, which is temperature dependent, can be calculated by the Arrhenius equation. Finally, experimental results were compared with good agreement to the numerical concentration profiles obtained by solving the continuity equation for each present ionic species coupled to the current law. © 2007 Thomas Telford Ltd.
