Abstract: “This study focuses on the level of adhesive filling around a post-installed anchor bolts in concrete. The level of adhesive filling was evaluated in a concrete specimen simulating adhesiontype post-installed anchor bolts using an elastic wave method (electromagnetic pulse method). As a result, it is found that the level of adhesive filling around a post-installed anchor bolts can be evaluated accurately by inputting elastic waves in the bolt and using the elastic wave energy received on concrete surface near the bolt.”
