AbstractPrestressed concrete pipe sections were corroded by the action of salt and the application of an anodic current in well-defined areas. A potential survey of the pipes was performed before they were buried on the grounds of the National Research Council of Canada urban infrastructure research site. After they were buried, pipe potentials were recorded using a reference electrode displaced at regular intervals on the ground surface directly above the pipe. Potentials were also measured using reference electrodes permanently embedded in the ground near the pipe. On the basis of the test data, a pipe potential survey from the surface of the ground could not be used to locatespecific areas damaged by corrosion.
