Abstract: The transport behaviour of chloride ion in concrete under external compressive load was
studied by using the test method and test rigs proposed by RILEM TC 246-TDC. The model
of chloride diffusion based on Fick's II law was used to illustrate the chloride diffusion of
concrete exposed to imposed compressive load. Further, based on the experimental results and
statistical output from former research, a probabilistic analysis was conducted to illustrate the
effect of external load, aging exponent and the critical chloride content on the reliability–
based service life of concrete under combined mechanical load and chloride diffusion.
