Study on Detection of Buried Steel Bar in Concrete with Electromagnetic Impact Driving Method

The authors devised a new method of detecting the location of a steel bar within concrete from the concrete surface by an electromagnetic impact driving method. Various experiments were performed to test the possibility of detection by this method. The amplitude characteristics of radiated sound from such a bar were also examined. Consequently, it is clear that the electromagnetic impact driving method is useful for detection of the location of a steel bar buried in concrete.
