Ultrasonic Pulse Velocity (UPV) testing is used to determine the integrity and quality of structural concrete or stone (up to 6 feet thick) by measuring the speed and attenuation of an ultrasonic wave passing through the element being tested. Areas with lower velocities typically have lower density and strength relative to high velocity areas.

The Ultrasonic Pulse Velocity (UPV) systems are designed to identify and map voids, honeycomb, cracks, delaminations, and other damage in concrete, wood, masonry, stone, ceramics, and metal materials. UPV tests are also performed to predict strength of early age concrete.

Ultrasonic Pulse Velocity (UPV) tests are performed to assess the condition of structural members with two-sided access such as elevated slabs, beams, and columns. Voids, honeycomb, cracks, delaminations, and other damage in concrete, wood, masonry, stone, ceramics, and metal materials can be identified and mapped with the method.

pulse velocity (UPV) method can be conveniently used to check the quality of stones and also for material characterization. Both the intrinsic characteristic of the stone (porosity, grain size, anisotropy, etc.) and the external factors (humidity, stress, temperature, presence of cracks)

The UPV method is used to map and detect voids, honeycombing, cracks, delaminations and other construction related failures in concrete. It can also be used to evaluate conditions in wood, masonry, ceramics, stone and metals.

2022年4月4日 · Ultrasonic pulse velocity test is performed on concrete to check their quality and homogeneity and also cracks, voids, cavities and defects in the concrete by passing electronic wave through the concrete. The apparatus used in the …

2015年7月1日 · UPV is used for non-destructive physical–mechanical evaluation of building stones. The study is carried out on a high porous limestone in dry and wet conditions. Water reduces UPV and especially compressive strength. Regression analysis shows a reliable correlation of UPV with compressive strength.

Water reduces UPV and especially compressive strength. Regression analysis shows a reliable correlation of UPV with compressive strength.

In this regard, ultrasonic pulse velocity (UPV) method can be usefully employed to investigate the properties and quality of the stone blocks within the masonry system [8–15]. Several factors may affect the measurements and relationships between UPV and mechanical and physical properties of the investigated stones.

2024年6月21日 · The UPV test measures the velocity of ultrasonic pulses traveling through the concrete. Discrepancies in pulse velocity can reveal the presence of defects. UPV testing for crack detection offers benefits such as non-destructiveness, precision, and cost-effectiveness.
