Abstract

Electrochemical chloride extraction from a reinforced concrete structure may be accompanied by an electrochemical injection of healing agents if such agents are positively charged and are able to migrate towards the activated reinforcement. Nanoparticles carrying a positive or cathionic corrosion inhibitors might be the proper choice. Organic substances with a positive charge and their salts are mostly such inhibitors. The essential conditions for successful application of such corrosion inhibitors are their sufficient corrosion inhibition efficiency that was studied and evaluated elsewhere and their stability of positive charge in alkaline concrete environment and their migration ability through concrete pore system.

Keywords: Concrete, corrosion inhibitors, chloride
