Note: Repair treatment used to combat carbonation-induced corrosion of steel in concrete and restore alkalinity. Realkalization, also known as electrochemical realkalization treatment (ERT), applies an electric field between the reinforcement in the concrete and an externally mounted anode mesh. An alkaline electrolyte is transported into the concrete, increasing the alkalinity of the cover zone, returning the steel reinforcement to a passive condition in the process.

Additional Notes: |
|
| Dutch ..... Reparatiebehandeling om door carbonatatie veroorzaakte corrosie van staal in beton te bestrijden en de alkaliciteit te herstellen. Bij realkalisatie wordt er een elektrisch veld toegepast tussen de wapening in het beton en een extern aangebracht anodenet. Een alkalische elektrolyt wordt in het beton getransporteerd, zodat de alkaliciteit van de overdekkingszone wordt verhoogd en de staalwapening weer in een passieve toestand komt. |
