Description
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.
