Overview

Electrochemical re-alkalization improves pH levels in concrete, suggesting a viable method to prevent corrosion in reinforcement.

Key Points

  • The treatment increased the pH of concrete samples to above 12.5, enhancing alkalinity and resulting in better protection against corrosion.
  • Electrochemical re-alkalization raised the compressive strength of concrete specimens by about 25%, indicating significant enhancement.
  • A current density of 1 A/m² was applied for 3 days using a selective electrolyte to effectively restore alkalinity.
  • The method demonstrates a non-destructive approach to mitigating corrosion in reinforced concrete due to carbonation and chloride.
