dc.description.abstractConcrete deterioration due to corrosion of the reinforcing steel is wreaking havoc on reinforced concrete structures world-wide. Replacing deteriorated structures is unsustainable financially and environmentally. Therefore, corrosion mitigation alternatives are imperative for extending the service life of our infrastructure moving forward. The following thesis investigates whether intermittent impressed current corrosion protection provides the same level of protection as a continuous impressed current system. A laboratory experiment evaluated four different impressed current levels (ranging from cathodic prevention to cathodic protection current densities) applied to concrete slabs. Each of the current levels had an intermittent and continuous group. It was found that there was no significant difference between intermittent and continuous protection. However, the high current groups did vary significantly from the control group and managed to achieve cathodic protection as per NACE standards. The continuous medium high and medium low groups were also found to vary significantly from the control group. As well, the majority of the experimental groups experienced a larger shift in corrosion potential in comparison to the control group, indicating a reduction in corrosion activity. Additionally, a field trial was conducted to evaluate whether solar panels could be used to power an intermittent system. Four locations were used; two were on the wingwalls which were the high light locations, and two were on the abutment walls which were the low light locations. Although all locations ran at cathodic prevention current densities, the high light locations managed to achieve cathodic protection, while the low light locations did not.en_US
