Cationic Corrosion Inhibitors and their Migration Ability in Real Concrete Specimens
Original language description
Corrosion of reinforcing steel is one of the main reasons of reinforced concrete structures deterioration, which is caused primarily by chlorides. Electrochemical chloride extraction (ECE) and electrochemical injection of corrosion inhibitor (EICI) are promising techniques eliminating this adverse effect. Both the techniques are based on application of electric field. Electrochemical chloride extraction from a reinforced concrete structure may be accompanied with an electrochemical injection of healing agents if such agents are positively charged and are able to migrate towards the activated reinforcement. The right choice can be positive charge carried by cationic corrosion inhibitors. Tests have been applied on real samples of concrete with various corrosion inhibitors using diffusion or migration methods. After the corrosion inhibitor application, the migration ability of the individual inhibitors was monitored. Comparison of migration ability of inhibitors was based on concentration profile in various depths. In addition to migration, corrosion inhibitors have been tested for sufficient corrosion inhibition efficiency that was studied in chloride containing concrete pore solution.
