Nowadays, the necessity of the NDT technique for concrete structure has been increased due to maintenance infra-structure. Therefore NDT instrument for automation of maintenance was focused from now. In this study, internal defeat of concrete structure was investigated by using ultrasonic detection device. In the result of the experimental test, the internal cavity and steel arrangement can be detected and it was possible to adopt the ultrasonic detection method to the maintenance of concrete structure.
