Structural Assessment and Long-term Durability Consideration of Concrete on Piers and Galleries of Chandil Dam using Non-destructive Test Method

Interaction of concrete with the persistent prevailing environmental condition will alter its material properties and cause deterioration. There are various causes distress in structure, such as improper construction practices, post-construction expansion due to Alkali-Aggregate Reaction (AAR), corrosion reinforcement, non-homogeneity concrete, development cracks shrinkage thermal stresses, aging, etc., Such phenomena very common elements dam. The aging structures their interactions conditions In spite maintaining best quality control, may not behave a homogeneous medium. Conducting any test modest way is key factor for true assessment status substratum. Diagnosis residual strength in-situ using non-destructive tests provides useful information adopting suitable preventive measures. Deteriorations can be broadly imaged ultrasonic pulse velocity technique. However, results depend on factors. Since prominent were observed pier, hence structural piers drainage galleries Chandil dam was required check concrete. this regard, Non-Destructive Tests (NDT) conducted dam, Jharkhand, by Ultrasonic Pulse Velocity (UPV) method assess
