Paper Abstract

The heterogeneities contained in concrete will cause strongly multiple scattering behaviors during the propagation of ultrasonic waves, forming the so-called coda waves. External loads will slightly change concrete structural size and further introduce stretching effects on coda waveforms. In this paper, coda waves are collected from several concrete samples under different loads, and the waveform variations are quantified through a stretching technique. The results show that their stretching ratios are varied according to external load strengths, which implies that stress changes in concrete can be detected by coda wave measurements. The presented study could be very value for nondestructive testing of concrete structures.
