Abstract: Infrastructure development is considered as a backbone for the development of any nation. Evaluation, maintenance, and repair of existing infrastructures need meticulous attention as well as substantial funds. Non-destructive techniques are extensively used for assessment of concrete structures to get accurate scientific insight on damages in less time. Ultrasonic pulse velocity test is one of the Non-destructive tests which are commonly used in the evaluation of concrete structures. A comprehensive study on modelling of ultrasonic waves, its propagation in concrete and behaviour on interfacial transition zone (ITZ) is not reported in the existing literature. As numerical models and simulation are in advance in the present computerised era, as a result, the study will act as a robust method for the design engineers to precisely simulate the UPV and compare with field assessment. In the study, concrete with different size of coarse aggregate ranging from 20 mm to 4.75 mm was modelled using ABAQUS with ITZ and voids. In addition, propagation of ultrasonic waves and resultant velocity were measured and compared with a concrete model which has only two sized coarse aggregates without interfacial transition zone. Results from the study show appropriate correlation with experimental observations.
