Paper Abstract

An investigation into the detection of voids in posttensioned concrete beams by ground penetrating radar is presented. Both experimental and numerical modelling results suggest that the optimum orientation of the radar's antennas is perpendicular to the long axis of the ducts containing the post-tensioning tendons.
