Steel reinforced concrete architecture performs an essential function in civil constructions including buildings, bridges as well as dams. Steel reinforcement provides stability of concrete structures, mechanical strength, and durability and so on. Contamination by chloride ions represents one of the most significant contributory factors to the induction of steel corrosion within a concrete medium. Chloride ions penetrating from the external surrounds have primary responsibility for development of rapid localized corrosion on steel rebar in concrete. Consequently, as these mechanical properties of the reinforcement concrete deteriorate, the long-term safety and performance of reinforced concrete structures can be negatively impacted to a significant extent. Inhibitors are one of the most methods used to prevent chloride ion to penetrate concrete. Amongst the most known inhibitors, organic compounds are prospective due to the presence of heteroatom like oxygen, nitrogen, sulfur and several bonds present in their molecules, responsible for the effective adsorption on the metal surface. Unfortunately, the compounds that constitute these inhibitors tend to be non-biodegradable, poisonous, and expensive to produce. In this regard, the exploitation of green nanoparticles (NPs) as corrosion inhibitor for steel reinforcement in aggressive environments remains unexplored. Nanoparticles are able to exert significant effects on the characteristics of a variety of substances due to their tiny size, mechanical, electromagnetic, optical and biochemical properties. Silver metal nanoparticles (AgNPs) in combination with plant extracts; have exhibited low toxicity, low expense and environmental acceptability when compared with more standard alternative chemical strategies. So, green nanoparticles compounds to can inhibit the corrosion of reinforcement process by developing a protective thin barrier upon the steel surface.
