Efficiency of Different Electrolytes on Electrochemical Chloride Extraction to Recover Concrete Structures under Chloride-Induced Corrosion

Figure 8

Corrosion values measured at each given charge passed during and after treatment in terms of (a) corrosion rate and (b) corrosion potential . Posttreatment values are depicted in the highlighted area of the graph to show that no current was applied in that interval; measurements were performed at 5 weeks to ensure the quality of results after depolarization time. (a) Corrosion rate values obtained by linear polarization at scan rate from −20 mV to +20 mV versus Ecorr at 10 mV/min and Stern and Geary equation. Mean values are given for each sample. (b) Corrosion potential values obtained by half-cell potential and the measurement of corrosion potential of rebar with respect to a saturated calomel electrode (SCE). Mean values are given for each sample.
