REMOTE SENSING OF AIR BLISTERS IN CONCRETE-FRP BOND LAYER USING IR THERMOGRAPHY

The paper discusses a study program that was undertaken of unbonded areas of concrete/FRP interface. The aim was to detect artificially induced air blisters in the bond line between FRP components and the RC beams. Additionally, the influence of air blisters on the flexural performance of FRP strengthened RC beams was evaluated. Infrared thermography was successfully used as a non-contact tool to locate the position of the blisters. The results indicate a curtailment of performance both in strength and ductility of the section as the area of blisters increased.
