Quality and Monitoring of Structural Rehabilitation Measures. Part 2: Review and Assessment of Non-destructive Testing (NDT) Techniques

This report, the second in a series, provides a state-of-the-art review of potential nondestructive testing (NDT) techniques for defect detection in carbon-fiber reinforced polymer (CFRP) materials through review of past and current projects, including industrial applications and research projects, as well as methods under current industrial development. Both theoretical and practical aspects of each individual technique are addressed, including information on equipment, portability, and data storage as well as their capabilities and limitations. Subsequently, these findings serve to assess the suitability of each individual method towards in-situ inspection of CFRP-rehabilitated concrete components.
