Abstract: Abstract: Plain cement concrete, fly ash concrete, and slag concrete with different water/binder (w/ b) ratios (0.35, 0.45, 0.55, and 0.65) were submitted to the accelerated chloride migration test (ACMT) and the ponding test. In the ACMT, the electrochemical technique is applied to accelerate chloride ion migration in concrete to estimate the chloride flux. The chloride migration coefficient for concrete was calculated using the constant flux on the basis of the Nernst-Planck equation. The total chloride contents and penetration depths were measured after the ponding test, and the Fick's second law of diffusion was fitted to the experimental data to determine the diffusion coefficient. The chloride migration coefficients from the ACMT and the diffusion coefficients from the ponding tests were compared. The results for all mixtures show that the migration coefficients and diffusion coefficients are linearly related.
