Evaluation of the effectiveness of electrochemical chloride extraction from concrete on the basis of testing reinforcement polarization and chloride
Szweda Z., Jaśniok T., Jaśniok M.
This paper refers to the evaluation of the effectiveness of electrochemical chloride extraction from concrete. The naturally slow process of chloride ingress into concrete cover was accelerated by chloride migration in the electric field. Later we performed the process of electrochemical chloride extraction. The process mechanism of reinforcement corrosion was tested by EIS during the process of chloride ingress into concrete, before and after the extraction process. After completing impedance measurements, concrete cover ground in layers was used to prepare model solutions of concrete pore water, in which chloride concentration and pH values were determined. The total analysis of impedance measurements of steel reinforcement, chloride and pH profiles in concrete was used to evaluate the effectiveness of electrochemical extraction. That treatment greatly reduced chloride concentration in concrete, but not always decreased corrosion rate of reinforcement.
