Abstract

An ongoing research program initiated in 1983 by Carino and Sansalone has been aimed at developing the theoretical basis and practical applications for a new nondestructive technique for detecting flaws in reinforced concrete structures. The technique, known as impact-echo, is well documented [1–6] and only a brief overview of the principle of the method, signal processing techniques, and instrumentation is presented. This paper highlights the results of a recent investigation into the feasibility of using the impact-echo technique to detect voids in plates containing thin layers of materials having different acoustic impedances.
