This paper investigates electrochemical phenomena induced during accelerated chloride diffusion tests using a migration cell. By monitoring of electrical current time evolution coupled with electrochemical impedance spectroscopy measurements, it was set that the electrical current measured between the two sides of cement-based samples during migration tests increases continually even after reaching steady state checked by a constant chloride flux at the downstream of the cell. This is found to be due to the decrease in the samples’ electrical impedance (resistance). Furthermore, the cell charge phenomenon which appears during polarisation was quantified through cell discharges in electrical resistors after polarisation.
