NDT Level II

NDT inspections are crucial for assuring and controlling the quality of components and structures during manufacturing and in-service inspections.

NDT needs to be used, to assess the quantum of damage to the concrete, as a material, either on the surface or sub–surface. Some equipment like Schmidt Hammer, Windsor Probe, Pull-off / Pull-out tests etc. provide QUANTITATIVE INFORMATION of the strength of concrete. It’s a known phenomenon that concrete carbonates as an ageing process. Carbonation turns the concrete into harder material on the surface. All the above NDT tests and similar other tests, have a higher degree of inaccuracy, since they measure the hardness / toughness / impact resistance of concrete. This increase in surface hardness / toughness and below the surface of concrete, due to the carbonation, without increasing the compression strength, challenges the fundamental principle of these tests, which increases the inaccuracy in carrying out the quantitative assessment of the compression strength of carbonated concrete using these NDT techniques.
