Description
This study focuses on the development of a method for preventing corrosion in RC structures by inducing current non-destructively and non-contactly into the internal reinforcing bars using the principles of electromagnetic induction. In this paper, firstly we conduct fundamental investigations into the characteristics of induced current on the reinforcing bar surface using experimental and analytical methods. Based on the results, we establish corrosion prevention conditions for this method (induced current density and power consumption). Next, we examine the corrosion prevention effect quantitatively for both macrocell and microcell corrosion in test specimens with multiple reinforcing bars. The findings demonstrate the effectiveness of this method against microcell corrosion.
