ULTRASONIC TESTING OF CONCRETE

ULTRASONIC TESTING OF CONCRETE

By KAUSHAL KISHORE Materials Engineer, Roorkee Fundamental principle A pulse of longitudinal vibrations is produced by an electroacoustical transducer, which is held in contact with one surface of the concrete under test. When the pulse generated is transmitted into the concrete from the transducer using a liquid coupling material such as grease or cellulose paste, [.]
