Stainless steel rebar is one of the most corrosion resistant reinforcing methods for concrete structures. Stainless steel is used for its chromium content and its ability to form a passive oxide corrosion resistant layer. The presence of chloride is one of the largest attackers of this passive film and able to penetrate concrete due to its porous characteristics. This study evaluates the mechanical performance of different stainless steels relative to their changing environments. It is expected that as chloride concentration values increase, mechanical properties will decrease. This will be tested by performing tensile tests on stainless steel rebar sample that is enclosed in a galvanic cell. Electrochemical tests such as Linear Polarization Resistance and Electrochemical Impedance Spectroscopy will also be performed during the tensile test to examine the relationship during this time. To this point, only results from the AISI 316 SS have been completed, showing that the 8% chloride concentration solution performed nearly 7.7% worse than the blank sample during mechanical tensile tests. An accurate relationship between mechanical properties and environment allows for more accurate life cycle costing analysis of materials during construction.
