    Effect of cation type of chloride salts, and sulfate ion on chloride diffusion, chloride binding and rebar corrosion in concrete containing corrosion inhibitors
    (2022) Das, Jyotish Kumar
    Corrosion damage of steel reinforcement embedded in concrete is one of the major factors that affects the durability and decreases the service life of reinforced concrete structures, which results in huge economic losses. Chloride ions are the primary cause for corrosion of steel reinforcement that leads to the deterioration and failure of reinforced concrete structures exposed to chloride-laden environment. The cation type of chloride salts plays a major role in the process of chloride ingress, chloride binding, and steel reinforcement corrosion in concrete. Further, sulfate ions also exist concomitantly with chloride ions in saline and marine environment. Due to huge repair costs for the corrosion damages in reinforced concrete structures, it is essential to effectively minimize the corrosion damage of reinforced concrete structures exposed to aggressive environment. Among different methods, the use of corrosion inhibitors is proved to be the long term efficient method to prevent corrosion of steel reinforcement due to several benefits such as convenience, cost-effectiveness, easy availability and high resistance to corrosion.
