Durability of reinforced concrete structures, Soundness diagnosis technique of infrastructures

During service, buildings made of reinforced concrete are exposed to various deterioration environments. Then, deterioration factors permeate through concrete, reach a steel bar, and initiate steel bar corrosion. Steel bar corrosion is a significant issue for structural performance and durability of reinforced concrete buildings. Many non-destructive electrochemical techniques have been proposed to detect initiation of steel bar corrosion from the surface of the cover concrete. However, measured data sometimes is not in accord with the actual state of corrosion because of the electrochemical properties difference of cover concrete. Hence, our group specializes in characterizing the electrochemical properties of cement-based materials. To tie practical techniques and our research achievement, we are focusing on laboratory experiments and field surveys of existing buildings.
