Abstract
This paper focuses on the effect of different temperature
levels on the chloride penetration through a saturated CEM I cementitious
materials. The temperatures studied were 5, 21 and 35 
C. In addition to
experiments, a model based on the 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 the marine environment
concentrations. The chloride diffusivity increases with the temperature on
the basis of the Arrhenius relation. Finally, experimental results are in
good agreement with the numerical profiles.
