Testing of Concrete Structures with Non-Destructive Test Method (NDT) Using Ultrasonic Pulse Velocity (UPV) at the Building on the Ancol Beach

CIVED
The UPV test procedure with the PUNDIT device is set based on the concept of the wave flow speed passing through a solid object bound to the elastic properties of a tangible medium. When used properly and correctly, this tool will provide a lot of information about the condition of the surface or the inside of the concrete.

Evaluating the effect of crumb rubber and nano silica on the properties of high volume fly ash roller compacted concrete pavement using non-destructive techniques

Case Studies in Construction Materials, 2018
The major problems related to roller compacted concrete (RCC) pavement are high rigidity, lower tensile strength which causes a tendency of cracking due to thermal or plastic shrinkage, flexural and fatigue loads.

Comparative Analysis of Acoustic Wave Velocity (AWV) and Ultrasonic Pulse Velocity (UPV) for Non-Destructive Evaluation of Fibre-Managed Eucalyptus nitens Logs and Recovered Samples

Forests
Testing harvested logs is a critical step in the wood products supply chain. Non-destructive evaluation (NDE) methods are essential for grading and sorting logs, especially given variations associated with tree age. In this study, plantation-grown Eucalyptus nitens from two age groups were sourced from two Tasmanian harvesting sites for NDE and ...
