Abstract: Reinforcement corrosion was the major cause of deterioration in reinforced concrete structures. Inhibitor is an effective way to mitigate corrosion of reinforced concrete. This study describes a laboratory investigation of the effectiveness of a newly prepared organic corrosion inhibitor (OCI) as corrosion inhibitor admixture for reinforced concrete. The inhibition efficiency of the OCI is evaluated by electrochemical tests in chloride-contaminated mortar samples with steel bars. In addition to this, the influence of OCI on the properties of fresh and hardened concrete was studied. It was indicated that this OCI could dramatically increase the resistance of steel to chloride attack and had no obvious influence on the properties of setting time and compressive strength. The newly prepared OCI was a promising inhibitor for concrete.
