RESULTS FOR NONDESTRUCTIVE TESTING OF CONCRETE


Nondestructive testing (NDT) methods are used to determine hardened concrete properties and to evaluate the condition of concrete in deep foundations, bridges, buildings, pavements, dams, and other concrete construction. NDT methods are applied to concrete construction to control quality of new construction, troubleshoot problems with new construction, evaluate condition of older concrete for rehabilitation purposes, and for quality assurance of concrete repairs. NDT methods include visual inspection, ultrasonic echo, and impact echo.
