This paper analyses the non-destructive testing (NDT) measurements used to assess on site strength and condition of reinforced concrete. To ascertain the residual strength of concrete, extent of corrosion, it is imperative to assess the health of the RC structural members of a building using State-of-the-art non-destructive testing (NDT). NDT of concrete structure is carried out in order to assess the health of structure without impairment of its desirable properties. The tests are mainly useful in understanding serviceability, adequacy of concrete, subsequently assessing the cause, extent of deterioration of structure and assessment of structural integrity or damage. Non-destructive testing (NDT) was aimed at assessment of condition of structural elements. In NDTs, rebound hammer and ultra-sonic concrete tests on columns has been carried out. Based on the detailed study and analysis of test data, appropriate remedial measures for repair and rehabilitation of damaged area are to be suggested.
