Abstract:  Performance steel bars, including continuous galvanized (ASTM A1094) and Low-Carbon Chromium Steel bars (ASTM A1035 CS), have been evaluated for their high corrosion resistance and the mechanism to extend the service life of concrete structures. ASTM A1094 is a galvanized rebar with a zinc alloy coating that provides the well-known corrosion protection of zinc and the added benefit of exceptional formability. ASTM A1094 can be bent and fabricated after galvanizing without fear of peeling or flaking. High Strength and Superior Blast Protection A1035-CS and CM rebar’s combination of high strength, corrosion resistance and ductility is proven to provide superior blast protection for concrete structures. The high strength can withstand stronger forces, while the ductility dissipates the force across the structural member. In addition, the high strength can be used to efficiently design structures up to 100 ksi (690 MPa) reducing construction costs and time. Corrosion studies are presented to illustrate the efficiency in using these bars to extend the service life of concrete structures depending on the required service life of the Hawaii reinforced concrete structures.
