The Effects of a Multifunctional Rust Inhibitor on the Rust Resistance Mechanism of Carbon Steel and the Properties of Concrete

To address rebar corrosion in existing concrete structures, a multifunctional compound rust inhibitor was developed. This study investigates the impact of this on carbon steel resistance, as well mechanical properties and durability concrete. The results demonstrate significant reduction weight loss when using inhibitor, with inhibition efficiency 82.6%. Scanning electron microscopy (SEM) atomic force (AFM) were employed to observe analyze surface elements steel, both without presence inhibitor. findings indicate that use leads smoother more stable film. experiments compressive strength, chloride ion electromobility, rapid carbonation test varying contents increasing amount can improve performance regulate mobility ions. Specifically, content reaches 4%, it has notable positive concrete, further increases lead results.
