Probing of Steel Bar Location inside Concrete using Multi-electrode Array

다전극 배열을 이용한 콘크리트 매립 철근의 위치탐사

Using numerical analysis modeling of Multi-electrode Array that could be applied to the corrosion state measurement of a reinforcing steel bar in concrete, the steel bar location inside concrete can be probed by the investigation of the change of the measured impedance from concrete surface determined by the electrical impedance of interface between the steel bar and concrete, the electrical resistivity of concrete, the array of electrodes and the relative location and diameter of the steel bar.
