Abstract
The basic method of verifying whether concrete complies with specification is to test its strength using cubes or cylinders made from samples of fresh concrete. It must be noted that non-compliance by a single test specimen or even by group, does not necessarily mean that the concrete from which the test specimens have been made is inferior to that specified; the engineer‟s reaction should be to investigate the concrete further. This necessitates Non-Destructive tests on the concrete in the structure. Nondestructive testing methods have been used on civil engineering structures such as dams and bridges since the 1960‟s. In NDT, the development has taken place to such an extent that it is now considered as a powerful method for evaluating existing concrete structure with regard to their strength, durability, investigation of crack depth, micro cracks and progressive deterioration are also studied by this method.
The aim of the present paper is to describe, how the NDT is done using ultrasonic pulse velocity for assessing concrete strength that are widely used in structural field. The main purpose of this test is to detect and identify defects in materials, measure its dimension and estimate its strength as well as to decide whether it is to be accepted or rejected.
