What is UPV test in concrete?
An ultrasonic pulse velocity (UPV) 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 concrete structure or natural rock formation.
Why is Upv tested for concrete?
Ultrasonic pulse velocity (UPV) test is used to check the quality of concrete also defects within concrete by passing electronic waves through the concrete. In general, UPV value increases with the increase in WFS content in concrete mixes as well as with age.
What is NDT method for concrete?
Non-destructive tests of concrete is a method to obtain the compressive strength and other properties of concrete from the existing structures. This test provides immediate results and actual strength and properties of concrete structure.
Is code for UPV test latest?
The Indian standard code i. e. IS code for ultrasonic pulse velocity test for concrete is IS 516 (Part-5 Sec-1) : 2018. The old IS code for the UPV test is IS 13311 Part-1.
How do you do a UPV test?
Ultrasonic Pulse Velocity Test for Concrete | Non-Destructive Testing
What does Upv measure?
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.
Why is Upv & RH test used?
Ultrasonic pulse velocity (UPV) and rebound hammer (RH) tests are often used for assessing the quality of concrete and estimation of its compressive strength. Several parameters influence this property of concrete as the type and size of aggregates, cement content, the implementation of concrete, etc.

What is Upv?
Is code for NDT test?
IS 13311-1: Method of Non-destructive testing of concret, Part 1: Ultrasonic pulse velocity.
How is UPV test calculated?
What are the 4 major NDT methods?
Visual NDT (VT) Ultrasonic NDT (UT) Radiography NDT (RT) Eddy Current NDT (ET)
Which NDT method is best?
The Best NDT Method for Welding
While many methods of nondestructive testing can detect failure-predictive flaws in welds, the most efficient, effective method is phased array ultrasonic testing.
Is code for pit test?
This standard covers the methods on non-destructive testing of all types of concrete piles covered in IS 2911 (Part l/Sections 1,2,3 and4 and Part III). The manner in which ‘Integrity Testing or Non- Destructive Testing (NDT)’ is currently used in this country is outlined in this standard.
What is NDT testing?
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
What is UPV test in civil engineering?
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.
Why NDT is called NDT?
NDT stands for Non-Destructive Testing. It refers to an array of inspection methods that allow inspectors to evaluate and collect data about a material, system, or component without permanently altering it.
What is DT test?
Destructive Testing (DT) As the name suggests, destructive testing (DT) includes methods where your material is broken down in order to determine mechanical properties, such as strength, toughness and hardness.
What is the purpose of pit test?
Test pits are holes dug prior to construction to help ensure the ground conditions are suitable for building projects. These test pits average a depth of 3-15 feet deep, and allow geotechnical engineers the opportunity to assess soil composition before officially breaking ground.
What is pile toe level?
Pile toe – A pile’s lowermost end. Redrive – A substantial number of impacts, or a substantial time of vibration, which significantly deepens the pile’s toe elevation.
What are 3 basic types of destructive testing?
The most common types of destructive testing methods are: Aggressive environment testing. Corrosion testing. Fracture and mechanical testing.
What are 3 types of destructive testing?
What is NDT and DT test?
Non-Destructive Testing (NDT) is used to collect information about a material in ways that do not alter it (i.e., without destroying it). Destructive Testing (DT) is used to collect information about a material in ways that do alter it (i.e., destroy it).
What is test pitting?
Pitting tests are used to evaluate the likelihood of a metal developing localized corrosion in the form of holes on its surface. Pitting tests are conducted with the use of various metal and solution combinations according to a governing standard (ASTM G48).
What are the 3 types of foundations?
Foundation types vary, but likely your house or home’s addition does or will have one of these three foundations: full or daylight basement, crawlspace, or concrete slab-on-grade.
