Reinforced concrete is extensively used as the construction material for its application, ease of construction and low cost. Deterioration of concrete is a natural phenomenon and has started exhibiting in a large number of structures an efficient approach is required in dealing with such problems. Identification of the causes of distress and consequent repair/ rehabilitation strategy at optimum cost is carried out by monitoring the structure. Structural health monitoring can be achieved by Non-destructive evaluation techniques. NDT is well known for assessing the in-situ strength of concrete without causing any damage to the structure.
