Abstract

The velocity of ultrasonic coda waves, the diffusive tail of ultrasonic signals, was monitored in a concrete specimen under uniaxial compression. The ultrasonic measurements were taken in two directions: parallel and perpendicular to the loading. A geophysical correlation-based approach called coda wave interferometery (CWI) was used to calculate the incremental stress-induced changes in velocities. Ultrasonic pulse velocities were also calculated using the conventional time-of-flight (TOF) approach. A comparison of TOF and CWI velocities revealed that the CWI velocities are more sensitive to the level of stress and damage within concrete, especially in low stress levels. Also, the CWI velocities measured parallel to the loading showed greater sensitivity.
