Abstract
Remote monitoring of a deterioration process has been studied through radar measurements of laboratory size concrete specimens representing conditions of concrete dams. The investigation includes manufacturing of concrete specimens which model different deterioration stages of a dam, radar measurements, and imaging of the specimens. The specimens have a delamination filled with air or water, which represent different physical conditions of a deteriorating dam. The change of the returned signals from the specimens is related to the condition change inside the concrete. The results show the feasibility of using a radar for monitoring the condition change of concrete dams at a distance.
