Abstract

Air-coupled impact-echo method for NDT of concrete is presented. In this study, air-coupled sensors are used to determine the thickness and find delaminations in concrete slabs with impact-echo approach. Test results show that air-coupled sensors work as effectively as contact impact-echo sensors when proper impactors are used. The air-coupled impact-echo test is then carried out on a concrete slab containing several artificial delaminations and voids. Evaluation of the degree of delaminations is successfully conducted using the air-coupled impact-echo method.
