In reinforced cement concrete the efficacy of physical phenomena of concrete is reformed with rebars, as its roles inherent in concrete for being moderate in thermal coefficient factor & highly ductile. However, when the assigned rebar in reinforced concrete confronts uncertain ingression of chloride ion concentration through any cracks due to excess service load, surface cracks due to shrinkage or cracks due to thermal variation, etc., the most possible damage to rebar's extant passive film morphology due to such exposure conditions would be irreversible corrosion. Hence corrosion itself, therefore should be fixated to prolong the life expectancy of any rebar induced concrete configuration. Advancement of technology significantly provides as many as elucidations to overcome rebar corrosion. Out of several rebar life spans increasing techniques, corrosion inhibitors are identified as most efficient technique by researchers against corrosion. However, majorly expensive & noxious corrosion inhibitors are being occupied in the construction industry. To articulate appropriate corrosion inhibitors, researchers of this paper have investigated on nontoxic eco friendly inhibitors system.
