In recent years the application of corrosion inhibitors to concrete has developed as a possibly effective method for corrosion prevention and the rehabilitation of corroded reinforced structures. In this project, corrosion inhibitors in concrete will be characterized, and their effectiveness evaluated. In particular, their long-term stability will be studied, and their distribution around the rebars in the concrete some time after application. Electrochemical measurements will be performed in simulated pore water, as well as on reinforced concrete specimens and structures. By means of potentiodynamic polarization and electrochemical impedance spectroscopy, the basic characteristics of behaviour of the steel in the simulated pore solution will be determined. The electrochemical noise technique, too, will be implemented in order to monitor the influence on the corrosion processes of the addition of different amounts of the inhibitor and/or chlorides. The second part of this investigation will be performed in the field, on a small concrete bridge and on the already rehabilitated columns of a viaduct. The results of the planned research work will be very helpful for further rehabilitation work on reinforced concrete structures in Slovenia. It is believed that the results of the project will improve our basic knowledge regarding the corrosion processes affecting steel in concrete, and the possibilities for their inhibition.
