Norcure® Re-Alkalization
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.
During the process an alkaline electrolyte, such as sodium or potassium carbonate solution, is transported into the concrete, increasing the alkalinity of the cover zone and the concrete surrounding the reinforcing steel. This process returns the steel reinforcement to a long-term passive, non-corroding condition.
