Title: Nondestructive Evaluation (NDE) of Structural Concrete With Stress Waves
Author(s): Larry D. Olson

Abstract:Case histories are presented to illustrate applications of nondestructive evaluation (NDE) methods that use stress waves to characterize the conditions of concrete construction. The case histories discuss the following NDE methods and applications: (1) impact echo to evaluate cracking in a 1923 thin-arch concrete dam on the downstream face; (2) ultrasonic pulse velocity to define the severity of cracking damage in precast bridge segments and for quality assurance of epoxy injection repairs; and (3) ultrasonic crosshole sonic logging with PC-based instrumentation for quality assurance of the integrity of concrete placement in drilled shaft and slurry wall foundations. Comparisons of NDE results defined the extent and nature of sound and defective concrete conditions.
