Abstract: abstract:In order to understand the relationship between the diffusion coefficient obtained from 90-day salt ponding test and the migration coefficient obtained from accelerated chloride migration test (ACMT; the electrochemical technique is applied to accelerate chloride ion migration), the transport properties of concrete obtained from those two methods are compared. The chloride profile was measured after ponding test, and the diffusion coefficient was calculated from the Fick's second law. The transport properties were calculated from the modified Fick's second law based on measurements of the penetration depth from colourimetric method after ponding test and ACMT. The experimental result shows that the diffusion coefficients obtained from ponding test correspond well with the migration coefficients. In ponding test, the diffusion coefficient obtained from the profile method and colourimetric method is linearly correlated.
