【 摘 要 】

Reinforcement corrosion in reinforced concrete structures results in significant reduction in durability and may cause premature failure. This study presents an experimental investigation ofcorrosion in reinforcing steel rebars with different binding types exposed to aggressive solutions of various concentrations under cathodic protection. The corrosion rate in the steel bars for different types of serial bindings was determined through their electrical current resistance. An increase in electrical current resistance represents an increase in corrosion at binding points with time. The study results indicate that the steel rebars under cathodic protection produced relatively less corrosion rate than those without any protection in the same aggressive solutions. The results also show that the type of binding in reinforcing steel has a great influence on corrosion rate.
