Electrochemical treatments directly address the cause of the corrosion activity by applying a high current density to the structure for a limited period of time. The selected electrolyte and the duration of the treatment depend on the cause of the corrosion problem. After the treatment is complete, the structure is left in a long-term passive condition with no further system maintenance or monitoring required.

 Norcure Electrochemical Chloride Extraction (ECE) is a treatment which a) extracts chloride ions from contaminated concrete and b) reinstates the passivity of steel reinforcement. Chloride extraction is carried out by temporarily applying an electric field between the reinforcement in the concrete and an externally mounted anode mesh. During the process chloride ions are transported out of the concrete. At the same time, electrolysis at the reinforcement surface produces a high pH environment. This process returns the steel reinforcement to a passive condition. Applications:
Features and Benefits:
Norcure Re-alkalization is a treatment that restores the alkalinity of carbonated concrete and reinstates the passivity of steel reinforcement. Re-alkalization is carried out by temporarily applying an electric field between the reinforcement in the concrete and an externally mounted anode mesh. When the process is complete, the pH of the concrete is greater than 10 which is sufficient to provide lasting protection to the reinforcing steel. Applications
