Abstract:

The objective of this project focused on the development of a hybrid nondestructive testing and evaluation (NDT&E) methodology that combines the benefits of microwave NDT and thermography into one new technique. In this way, unique features of both NDT methods can be brought together to achieve new results that one method alone cannot achieve. Preliminary results have shown the combination of microwave and IR methods as a promising technique for detection corrosion in metals. The objective of this project is to build upon these preliminary results to investigate the feasibility of this new technique, herein referred to as Active Microwave Thermography (AMT), to detect and evaluate the presence of corrosion in cement-based materials (e.g., corrosion of reinforcing steel bars, or rebar), which is of critical importance to the nation’s transportation infrastructure. Included in this investigation was the acquisition of a small AMT system (designed and built by the graduate student supported by this project) to allow investigators to perform properly controlled experiments with consideration given to incident microwave power, distribution of the microwave energy, frequency, polarization of the incident signal, etc.
