It becomes sometimes necessary to examine the hardened concrete structure for their suitability for its intended use. But the examination of such existing or new structures should be such that it is not damaged during the process. In such cases, the Non-destructive test methods are used for testing of concrete structures.
There are various NDT tests available for concrete structures, but based on its suitability and applications they are selected. These tests can be completely non-destructive, or partially destructive tests which may not have much effect on the strength and durability of concrete structure. you can obtained by here MNT one of the best Civil ndt course in Chennai.

Visual inspection of concrete structure is carried out before any intended non-destructive test. Visual inspections provides information on type of concrete damage, their possible causes and type of NDT test suitable for further investigation. Visual inspection is carried out by experienced civil engineers who can interpret information from the damages in the concrete structure.
Schmidt NDT Test or Rebound Hammer Test, is carried out for the evaluation of surface hardness of concrete structures. The surface hardness of concrete is the indication of strength of concrete.
Carbonation depth measurement test – This NDT is used to determine the penetration of moisture inside concrete. This helps in identifying the moisture reaching the reinforcement which may cause corrosion.
Permeability test of concrete structure is to find the permeability which is the measure of flow of water through the concrete.
Penetration resistance or Windsor probe test, used to measure the surface hardness and hence the strength of the surface and near surface layers of the concrete.
Half-cell electrical potential method- This NDT test is used to detect the corrosion potential of reinforcing bars in concrete.
