Corrosion Performance Overview of Existing Concrete Reinforcement Options

Previous research has examined the corrosion resistance properties of different concrete reinforcement options (e.g., ChromX, hot dip galvanized, continuous hot dip galvanized, epoxy coated, black steel). But further work is needed to understand the behavior of rebar when exposed to chlorides. With better data on reinforcing steel performance, Kentucky Transportation Cabinet's (KYTC's) Division of Structures can incorporate more effective rebar into the design of structures with an eye toward reducing future maintenance costs. Exposing rebar samples to chlorides and accelerated weathering in a salt-fog chamber is a useful testing strategy for determining to what extent reinforcing steel resists corrosion. The project will identify concrete reinforcement options (i.e., type and size) to analyze, perform accelerated weathering testing and evaluate rebars for loss of material, and test pre- and post-accelerated weathering samples to assess variations in mass and tensile properties (i.e., tensile strength, yield strength, percent elongation).
