An ultrasonic pulse velocity test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a …

The ultrasonic pulse velocity test is a non-destructive test used to determine the quality of concrete on site. This test basically involves the assessment of the velocity of electronic pulse passing through the concrete from a transmitting transducer to a receiver transducer.

Ultrasonic testing of concrete or ultrasonic pulse velocity test on concrete is a non-destructive test to assess the homogeneity and integrity of concrete. With this ultrasonic test on concrete, following can be assessed: Qualitative assessment of strength of concrete, its gradation in ...

This test is done to assess the quality of concrete by ultrasonic pulse velocity method as per IS: 13311 (Part 1) – 1992. The underlying principle of this test is – The method consists of measuring the time of travel of an ultrasonic pulse passing through the concrete being tested.

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 …

2024年5月3日 · Ultrasonic Pulse Velocity (UPV) is an efficient non-destructive testing (NDT) technique for ensuring concrete material quality and identifying structural component damage. Traditionally, the UPV techniques have been employed for material quality control, primarily for homogeneous materials like metals and welded joints.

A UPV test is a nondestructive test that determines the calibre of concrete, evaluated by computing the velocity of an ultrasonic pulse that passes through a concrete specimen or natural rock formation [147].

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 UPV Test measures the time of travel of an ultrasonic pulse passing through the concrete. The high UPV Test and lower time of travel indicate good quality of concrete in terms of density, uniformity, homogeneity, etc.

Ultrasonic Pulse Velocity (UPV) test is one of the non-destructive tests. It detects cracks, strength of concrete and other properties of concretes. It is portable and easy for testing. Since UPV use velocity principle testing method, hence the frequency of the velocity should be consider too when taking measurement on different material.
