Replacement of Steel Rod by Stainless Steel

Abstract

In concrete structures with great levels of chlorides, e.g., in nautical environments, stainless steels generally deal an exceptional marginal where other metallic materials are exposed to corrosion. Stainless steel is designated for its corrosion confrontation, strength and long life. The upsurge in installed cost using stainless steel reinforcing bar ranges from one to fifteen percent depending on structure complexity. When Life Cycle Cost and longer reinforcing bar life of up to 125 years are factored in stainless steel is very cost effective. Stainless steel reinforcing bar is being used for highway bridge decks, overpasses, tunnels, retaining walls and restoration projects where corrosive conditions could cause premature failure of carbon steel reinforced concrete resulting in potentially severe damage and high repair costs. Emphasis will be placed on the mechanical and physical properties of stainless steel compared to carbon steel rebar as this information is important to those who wish to specify stainless steel reinforcing bar. Also, some stainless rebar applications around the World will be recognized. In addition, a description of laboratory and field tests, involved.
