A Study on Non-Destructive Testing of Government Polytechnic Jehanabad Building Using Rebound Hammer

In recent years, innovative NDT methods, which can be used for the assessment of existing structures, have become available for concrete structures. The purpose of establishing standard procedures for non-destructive testing (NDT) of concrete structures is to qualify and quantify the material properties of in-situ concrete without intrusively examining the material properties. There are many techniques that are currently being research for the NDT of materials today. This study presents the compressive strength of a Non-Destructive Testing (NDT) investigation conducted on the Government Polytechnic Jehanabad building using the Rebound Hammer Test. The primary objective was to assess the surface hardness and estimate the in-situ compressive strength of concrete structural members without causing any physical damage. Concrete compressive strength is one of the most important concrete requirements that can be used to decide if the concrete is structurally acceptable or not. Compressive strength of concrete depends on age of concrete, moisture content, surface carbonation etc. This study provides valuable insights into the current condition of the institution’s structure and highlights the importance of regular NDT assessments
