ACOUSTIC EMISSIONS TESTING OF PRESTRESSED CONCRETE IN AN ACCELERATED STATE OF CORROSION

Summary:
The acoustic emission (AE) testing reported herein was conducted on a large size prestressed concrete slab placed in contact with sea water in a state of electrically induced accelerated corrosion. AE signals were monitored and successfully analyzed in an attempt to evaluate the severity of the deformation process in the concrete as a result of the corrosion induced cracking. Several features of the AE data which were sensitive to the process were plotted to show the different levels of the cracking due to the corrosion. These were amplitude, counts and energy distributions, and event distribution with time. A location test was employed to find the source of the activities. The results of the amplitude distributions were found to have similar characteristics to those obtained from the reinforced concrete AE experiments performed at Florida Atlantic University (1,2). These tests can be easily applied to a field location for an early detection of the deformation process in the concrete structures.
