The utilization of concrete is exponentially increased for the development of infrastructure such as power plants, Irrigation structures, bridges, etc. Concrete undergoes deterioration due to corrosion of reinforcement, ageing, and other environmental conditions. For deteriorated concrete, it is necessary to evaluate to assess the state of concrete and reinforcement would help in selecting proper remedial measures. The condition assessment of old and new concrete structures can be done using Non-destructive testing methods. These NDT techniques can play a supporting role in the decision-making process of the conditional assessment of the structure. NDT methods are preferred because they will not alter the appearance or functionality of the structure. The testing of existing structures is usually related to an assessment of structural integrity or adequacy. The main objective of this workshop is on the NDT methods used for the condition assessment of concrete structures.
