CORROSION-RESISTANT STEEL REINFORCING BARS
This Innovations Deserving Exploratory Analysis (IDEA) project evaluated the corrosion resistance and mechanical properties of steel rebars produced by new microalloying and rolling procedures. Tests results confirmed that microalloying significantly decreased the corrosion rate of steel, and that quenching and tempering heat treatment further enhanced its corrosion resistance as well as yield and tensile strengths. Implementation of the new reinforcing steel will require extensive field validation, the development of standard specifications for the material, and the execution of demonstration projects in which the new reinforcing steel is applied in practice. Special attention should be given to using the new steel in conjunction with epoxy coating.
