INSTANTANEOUS DETECTION AND MECHANICAL BEHAVIOR OF MICROCRACKING IN CONCRETE

Investigations of microcracking in concrete specimens were made by detecting elastic waves as signals of cracking by means of a crystal microphone under simple compression, sustained compression and flexure. The cracking occurred at a load much less than that generally recognized. Under short time sustained load, cracking signals increased abruptly at 85 percent of the ultimate load, which corresponds to a critical point in creep of concrete. /Author/
