Introduction -- Summary of methods -- Planning and performing investigations -- Visual inspection -- Stress wave methods -- Pullout and pull-off methods -- Break-off method -- Penetration resistance -- Ultrasonic pulse velocity -- Rebound method -- Magnetic and electrical methods -- Radiography -- Infrared thermography.

Provides comprehensive guidance on the selection, application, interpretation, and limitations of nondestructive test (NDT) methods used for evaluating concrete in structures. The report reviews visual inspection techniques, stress-wave methods, rebound hammer testing, penetration resistance, pullout tests, maturity methods, magnetic and electrical techniques, radiography, infrared thermography, acoustic emission, and in-place testing procedures. It discusses planning and execution of investigations, data interpretation, reliability of test results, and appropriate use of NDT for assessing concrete quality, strength, durability, defects, and structural condition. Intended for engineers, inspectors, researchers, and professionals involved in the evaluation and maintenance of concrete structures.
