Evaluation of Steel Reinforcing Bar in Concrete Using Electromagnetic Method
2018-07-06
We developed electromagnetic methods to evaluate the steel reinforcing bar in concrete. Using two probes and lower excitation frequencies of 3.8 k Hz and 4.2 k Hz, the depth and the diameter of the steel reinforcing bar can be evaluated and the resolution of better than 1 mm is obtained. Using higher excitation frequency of about 80 kHz, the corrosion of the steel reinforcing bar can be evaluated.
