Accelerated corrosion of steel in dry-cast reinforced concrete pipes after initiation

Instrumented dry-cast reinforced concrete pipe (DC-RCP) specimens in which
corrosion of the reinforcing steel had initiated were selected to accelerate the corrosion.
Type C and type F DC-RCP were used. An anodic current density of various magnitudes
(0.5 μA/cm2, 1 μA/cm2 and 2.5 μA/cm2) was applied during the corrosion propagation
stage. The specimens were placed in high humidity and selected specimens were later
covered with wet sand. Selected specimens were terminated for visual examination and
gravimetric analysis. Typically, the reinforcement potentials during the accelerated
corrosion period were more negative for F specimens compared to C specimens. The C
specimens experienced ~2× more corrosion than the F specimens. The accumulated
corrosion products did not cause cracks. A method was developed that allows for modest
corrosion acceleration during the corrosion propagation stage of DC-RCP. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection
