As infrastructures are being deteriorated, non-destructive evaluation of existing structures and construction quality control are increasingly demanded. This paper is aimed to study flaw detection technique of concrete members using impact echo method, which is one of the non-destructive test methods. This technique is based on stress wave propagation. For the damage detection of existing concrete structures, concrete slab specimens was prepared, and various tests were conducted for the study of the behavior of stress waves. The concrete slab members of the flaw detection consist of 5 types; one group for the thickness tests, one group for the position of the void, one group for the position of the steel bar, one group for the recognition of steel plate buried in the specimen, and one group for the recognition of the PVC pipe buried in it. Experiments were performed using five types of concrete slab members that have simulated damages at known locations for tests and analysis. Test results are evaluated and summarized in this paper. |
