Structures sometimes suffer from corrosive deterioration during their long service. In order to meet the increasing needs to protect structures from corrosion and further prolong service life, a variety of new diagnostic techniques have been developed as essential tools in the area of structural maintenance.
This paper outlines several examples of such techniques that have been produced as the results of our R/D efforts. Particularly notable are the corrosion monitoring devices such as (1) a corrosion sensor for marine steel structure, (2) a sensor for detecting corrosion of reinforcing bar in concrete and (3) a diagnostic sensor to monitor the corrosion protectivity of the rust forms on weathering steel.
These sensors utilize the most advanced electrochemical techniques to provide meaningful data for quick and accurate corrosion diagnosis and are expected to play increasingly important roles on various diagnostic fields in the future.
