Description
Steel reinforced concrete beams were placed in contact with
seawater in a state of accelerated corrosion, for varying
periods of time. Some of them were simultaneously monitored
for acoustic emission and the results were analyzed to
evaluate the effectiveness of acoustic emission as a
non-destructive monitor of corrosion induced damage. It was
shown that, in a laboratory environment, counts are good
indicators of the extent of corrosion damage. A review of
acoustic emission monitoring techniques and theoretical
background is included. The concrete beams were tested for
flexural strength after being corroded. Reduction in rebar
section was found to have a very good correlation with
da mage. An attempt was made to predict remaining life of
the beams based on data obtained from the tests.
