In this paper an attempt was made to establish Non Destructive testing technique for the estimate of compressive strength of M25 grade of concrete using different types of fibers (Steel and Glass fibers). Beam-column joint connections are crucial in framed structures because they play a crucial role in the load-carrying moments of reinforced concrete structures.This paper presents two NDTs - Ultrasonic Pulse Velocity tool (PUNDIT) and Schmidt rebound hammer test done on beam column joints connections, in this paper is about evaluating the beam column joint connections in different fibers using NDT. Laboratory experiments and other test data from the literature were used to gather the data that was used to determine the values and test the model. To increase the joints' ability to resist forces, numerous researchers have studied joints utilizing various methodologies, materials, and healing approaches.According to the literature, steel and polypropylene fibers have improved a number of concrete's desired qualities. In our research paper a comparison study was made on polyprolene and steel fibers using Non destructive method.
