Stainless Steel-Reinforced Concrete (SSRC): a Review

Reinforced steel corrosion in concrete and masonry buildings is so common that it has earned the moniker “Concrete Cancer” to describe the phenomenon. Corrosion causes many cracks and concrete spalling, eventually bringing down the lifetime of the building. RC buildings are more expensive to repair and maintain, and the resulting vibrations can be harmful to the sustainability of the remaining structure. Taking measures to reduce corrosion, such as raising the cover or applying anti-corrosion coatings, will result in larger section sizes, higher construction costs, and weakened bonds. Stainless steel is used as reinforcement because it is more corrosion-resistant, has a longer lifespan, and requires less maintenance. In comparison to regular steel, it has improved ductility and strain-hardening capabilities. While the cost of this stainless steel may be higher than that of mild steel at the outset, it will require far less upkeep over time. Compared to conventional RC buildings, the lifespan of those made with stainless steel reinforcement is doubled. More study is being devoted to this stainless steel-reinforced concrete because of the current emphasis on “Sustainable infrastructure.” This paper provides a concise overview of the material and structural features of SSRC, an in-depth examination of the already available data, and a discussion of where further study is needed.
