Utilization of NDI to inspect internal defects in reinforced concrete structures
The amount of concrete structures has increased tremendously in Japan since 1960. Due to the increase of the structures in use for more than 30 years, evaluation of the structures is becoming an important task for the civil engineers to specify when and how to repair or to strengthen the structures. To deal with the problem, non-destructive inspection technique is becoming more and more important, both for overall inspection and detailed inspection. The paper describes the present situation in Japan how the inspection is being done using NDI, and also introduces some of the newest techniques, such as thermograph, multi-spectral image sensing, ultrasonic inspection, etc., developed in Japan. As shown in the experimental works, the individual NDI has its own characteristics. The methods described here are only a part of the work being done by the research committee of NDT in IIS, University of Tokyo. There may be other methods for detailed inspection, but it is important to recognize the difference and possibility of the NDI even in case of reinforced concrete.
