Study of Corrosion Inhibitors (Pennisetum Glaucum extracts) on Mild Steel used in Building Construction

Corrosion of Mild steel IS: 432 (Part I)-1982 in various concentrations of hydrochloric acid and sulphuric acid are studied by Mass Loss method in the absence and presence of the extracts of seeds plant Pennisetum glaucum (Pearl Millet). Corrosion relates effects the technologies. Water plays an important role in enhancing corrosion. In this paper the mass loss equation, concludes that corrosion inhibition increased to proportionate concentration of the extract. It has been found that seed extract of plant Pennisetum glaucum is the effective and have high corrosion inhibition efficacy. It was also observed that mild steel is more susceptible in acid like HCl and H2SO4 solution.
