UPV method in non-destructive testing for concrete is used to determin...
Ultrasonic Pulse velocity method deals with the noting of time of travel of electronically generated mechanical pulse which is further used to analyse the velocity of pulse through the structure that represents its quality.
This test is used to establish uniformity of concrete, estimation of pulse modulus of elasticity, estimation of strength of concrete, determination of setting characteristics of concrete, estimation of crack depth, measurement of thickness of concrete pavement. This test calculates dynamic modulus of elasticity of concrete.
This test does not estimate tensile strength of concrete, so option a, b, d are wrong. So, correct answer is option c.

B
b<1. compressive="" strength:="">
The UPV (Ultrasonic Pulse Velocity) method is commonly used to determine the compressive strength of concrete. In this method, ultrasonic pulses are transmitted through the concrete and the time it takes for the pulse to travel through the concrete is measured. The velocity of the pulse is directly related to the compressive strength of the concrete. The higher the velocity, the higher the compressive strength.
b<2. existence="" of="" voids:="">
The UPV method can also be used to detect the existence of voids in concrete. When an ultrasonic pulse encounters a void or air pocket within the concrete, it will travel at a different velocity compared to when it travels through solid concrete. By analyzing the changes in pulse velocity, the presence of voids can be identified.
b<3. tensile="" strength:="">
The UPV method is not typically used to directly determine the tensile strength of concrete. Tensile strength testing usually requires destructive testing methods such as the splitting test or the flexural test.
b<4. static="" modulus="" of="" concrete:="">
The UPV method can be used to estimate the static modulus of concrete. The static modulus is a measure of the stiffness of the concrete and is an important parameter in structural analysis and design. By measuring the pulse velocity and knowing the density of the concrete, the static modulus can be estimated using empirical relationships.
b<5. dynamic="" modulus="" of="" concrete:="">
The UPV method can also be used to estimate the dynamic modulus of concrete. The dynamic modulus is a measure of the concrete's ability to resist deformation under dynamic loads. By measuring the pulse velocity and knowing the density of the concrete, the dynamic modulus can be estimated using empirical relationships.
b
In summary, the UPV method in non-destructive testing for concrete is primarily used to determine the compressive strength and the existence of voids. It can also be used to estimate the static modulus and the dynamic modulus of concrete. However, it is not typically used to directly determine the tensile strength of concrete.
