Description
Surface cracks are one of the most commonly observed distresses in concrete structures. Even though the crack depth is an important parameter to evaluate the depth of degradation and section capacity, only crack length and width are commonly documented. The typical ultrasonic pulse velocity (UPV)-based test setup available for crack depth measurement uses compression waves and two transducers, as a transmitter and a receiver. Since the crack depth measurement uses an indirect mode of transmission and requires a good coupling with the concrete surface, the implementation of this system is challenging. In this study, the feasibility of using a commercially available ultrasonic tomography equipment with an array of dry-point-contact shear wave transducers to estimate the depth of concrete surface opening cracks was evaluated under laboratory conditions. UPV data was collected on three concrete slab …
