| Abstract: | Elastic wave-based non-destructive testing(NDT) methods are effective for flaw detection in concrete structures and pavements.However,the test speed of elastic wave-based methods is severely limited by the physical coupling between sensors and concrete surface.The air-coupled sensing method is proposed as a solution to develop rapid NDT techniques for concrete infrastructure.This paper reviews the development of air-coupled sensing technique for concrete structures in civil engineering applications.It prese... |
