Recent Advances of Microwave Nondestructive Testing Techniques in Concrete Structures
Recent advances of microwave nondestructive testing techniques in concrete structures are reviewed. A near-field microwave nondestructive testing technique for disbond/crack detection and evaluation in a concrete structure backed by an infinite half space of any material is presented. A fuzzy logic model relating the phase of reflection coefficient, frequency of operation, and standoff distance to the disbond thickness and depth was generated and utilized. A simple near-field microwave nondestructive inspection technique for segregation detection in concrete members is presented. An Inverse Synthetic Aperture Radar system has been applied to laboratory size concrete specimens to investigate its capability of generating cross range imagery and to explore potential of the system for nondestructive testing of concrete structures. Finally the technical challenges and developing prospect of microwave nondestructive testing technique in concrete structures are discussed.
