What about stray currents with SFRC?

Stray Currents: Definition
  • Stray currents arise from rail transit systems, cathodic protection systems, or high-voltage power lines.
  • Stray currents may be DC or AC depending upon the source. Stray DCs are known to be much more dangerous than stray ACs.
  • In case of DC, a cathodic reaction (e.g. oxygen reduction or hydrogen evolution) takes place, where the current enters the structure (or, reinforcement), while an anodic reaction takes place (e.g. metal dissolution), where the current returns to the original path, through the soil (or, concrete).
