Abstract

In the paper along with Case studies Buildings and structures are normally designed for a specified target life based on the functional and economical aspects. It is due to the fact that the assumptions are made regarding durability of material without knowing the behaviour of material completely in real environment. The various tests are to be carried out to assess the causes & extent of distress, the quality/strength of concrete and adequacy of structure. The paper briefly discusses various NDT techniques such as Rebound Hammer, Ultrasonic Pulse Velocity, Carbonation Test, Rebar Locator Test & Impact Echo Test, Radiographic, and Magnetic Particle Inspection from a practical standpoint of an experienced Structural Engineer along with some partial-destructive testing methods. The existing non-destructive testing techniques that are being used for detection of defects are compared with the alternative techniques. It is quick and relatively uncomplicated, It gives immediate indications of defects, It shows surface and near surface faults, and these are the most solemn ones as they concentrate stresses, The method can be adapted for site or workshop use, It is inexpensive compared to radiography, Large or small objects can be examined, Elaborate pre-cleaning is not necessary. Hence we use magnetic particle inspection method.

Keywords: Non- destructive testing, maintenance, Repair, Rehabilitation, Radiographic, and
