Quantitative nondestructive evaluation technique of anchorage zone of post-installed anchors by using electromagnetic pulse method is presented. For quantitative evaluation, several indexes are introduced, which are derived from received signals and their frequency spectra. The effectiveness of the technique is demonstrated by experiments using anchors installed in concrete test blocks and also those installed in an existing building.
