Identifying Radius of Rebar Buried in Concrete Massif by Using Electromagnetic Penetrating Radar

Abstract:

In this work, identification of rebar radius for a single steel reinforcement buried in a concrete member was investigated. A method based on electromagnetic penetrating radar was proposed. The principle of this method consists of working with adequate high frequency antennas that emit short pulses and measure the reflected echoes from the discontinuities present inside the medium. Image post-processing of the obtained B-scan radargrams enabled to extract essential information which has facilitated the derivation of a correlation formula to estimate the rebar radius. Predictions made by this formula were found to achieve better accuracy than previously known methods.
