Various types of reinforced concrete structures (such as viaducts, bridges and tunnels) in the neighborhoods of railways may be subjected to stray current leaking from the rails. Compared with stray current induced corrosion of pipeline, reinforced concrete has relatively more problems to deal with: the volume of corrosion product gradually increases, the induced pressure around the embedded steel can lead to cracking, spalling or delamination. This finally may lead to the failure of the whole structure.

Various points related to stray current interference on reinforcing steel were investigated and clarified in this research project:

  • Different effects of stray current and anodic polarization on corrosion performance (resistance) of embedded reinforcing steel;
  • Bond behavior of steel-mortar interface affected by stray current;
  • The importance of steel orientation with respect to the electrical field placed parallel or orthogonal to the current direction;
  • Transient response and corrosion monitoring of reinforcing steel embedded in mortar undergoing stray current interference.
