Scope of the Report

This NACE report contains information about materials that provide a corrosion-resistant alternative to plain carbon steel reinforcing bar (rebar), known also as black bar. Throughout this report the term "carbon steel bar" is used to refer to the plain carbon steel reinforcing bar. Emphasis is given on materials that have actual, or potentially, wide commercial availability. Information on fabrication, detailing, and placement of commercially available corrosion-resistant steel reinforcement is given elsewhere.¹

Each material is briefly described, indicating the principles for its corrosion resistance, applicable chemical composition and standards, manufacturing method, history of application and current availability, and extent of use. Field and laboratory performance is described with attention whenever possible to quantitative consideration of the parameters that determine durability relative to that of plain carbon steel bar. ASTM⁽¹⁾ standards referenced in this report are listed in alphabetical order in Appendix A; however, the international user can refer to relevant standards applicable in his/her country.
