Investigation of quality of thick concrete by ultrasonic pulse propagation
Velocity of ultrasonic pulses through concrete is measured by oscillograph timing technique; to increase range about 8 ft through good quality concrete with standard instrument, higher power, and low frequency, sharply directional magnetostriction transducers were used in tests; 20 ft is maximum path length possible with this method.
