| Research Abstract |
In order to investigate the corrosion state of reinforced concrete structures by non-destructive method, the method of resistivity measurement in the concrete material was adopted. In the present research, it is clear that the resitivity was decreased in case the reinforced bars were under concrete surface measured. Moreover, Dipole-Dipole method is appropriate for the case that electrode array is perpendicular to the direction of bar arrangement. On the other hand, Wenner method is well applied to the parallel direction of bar arrangement against the ekctrode array.
