COMPARISON OF FIVE STANDARDS ON ULTRASONIC PULSE VELOCITY TESTING OF CONCRETE

The essence of the pulse velocity method is that the transition time of an ultrasonic longitudinal pulse (wave) is measured in concrete. The pulse velocity is then computed and inferences are made regarding the strength or overall quality, or both, of the concrete. This procedure has been standardized and five such procedures are compared in this paper, including the American, British, German, Russian, and Slovak standards. Investigators found that the most reliable applications of the ultrasonic pulse velocity method are for checking the uniformity of concrete and monitoring the changes in a concrete with time. Strength estimation is possible, but only under strict laboratory conditions. Other applications--defect detection and crack depth measurements--are even less reliable. No notation is made in any of the examined standards about the unreliability of most of the applications. This comparison is intended to help in the better use of the ultrasonic pulse velocity method and to contribute to the improvement of future standards.
