Abstract

The paper presents experimental results of damage growth during cyclic loading of concrete. The damage growth is inferred from the reduction in amplitude of ultrasonic waveforms transmitted through the specimen during the test. The amplitude of the waveform, by virtue of its higher sensitivity to the extent of cracking, is found to be a better indicator of crack growth than the more often used pulse-velocity technique. A continuous recording of pulse transmission throughout the tests is obtained by using a pulse generator, a digital oscilloscope, and a microcomputer. The damage accumulation during cyclic loading is inferred from the attenuation results is presented for several mix proportions.
