摘要 The effective evaluation of transport phenomenon of chloride-ions in concrete is required in any study of the durability problem of concrete members and structures. In this paper, the analytical solution of the Nernst-Planck equation in cylindrical space with radial symmetry and time coordinates compared with the results of the accelerated chloride migration test (ACMT) obtained from the literature were used to investigate the transport phenomenon of chloride-ions in concrete. The diffusion/migration coefficient of chloride ion was calculated by the analytical solution of the proposed method and compared with the previous results of the ACMT. The results of the present study show that the pozzolanic materials such as fly ash and slag could reduce the chloride permeability in concrete. Both the chloride concentration and migration rate versus time obtained by the calculation of the Nernst-Planck equation in two-dimensional cylindrical space and time coordinates are distinguishably in good agreement with the results measured from the experiment of the ACMT taken from the literature.
