Study of Destructive and Non-Destructive Test for Codal Base Minimum Grade of Concrete
The use of NDT increase safety and allows better schedules of construction thus making it possible to progress faster and economical. In this project the study of destructive and non-destructive test on concrete specimen. The destructive test taken on cube, cylinder and beam. The non-destructive test taken on cube, cylinder and beam. From the non-destructive test found out the accurate result of the concrete strength. Today modern non-destructive tests are used in manufacturing, fabrication and in service inspections to ensure product integrity and reliability, to control manufacturing processes, lower production costs and to maintain a uniform quality level. During construction, NDT is used to ensure the quality of materials and joining processes during the fabrication and erection phases, and in service NDT inspections are used to ensure that the products in use continue to have integrity necessary to ensure their usefulness and the safety of the public. It should be noted that while the medical field uses many of the same processes, the term NDT is generally not used to describe medical application. NDT is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used. In contrast to NDT, other test is destructive in nature and are therefore done on a limited number of samples, rather than on the material, components or assemblies actually being put into service. These destructive tests are often used to determine the physical properties of materials such as impact resistance, ductility, yield and ultimate tensile strength, fracture toughness and fatigue strength, but discontinuities and differences in material characteristics are more effectively found by NDT.
