Abstract
This paper studies effects of the leaf-extract of Morinda lucida on the corrosion-degradation of steel-reinforced concrete in 3.5% NaCl, simulating saline/marine environment (prevalent in offshore environments for wind-energy structures/installations). Electrochemical monitoring techniques and compressive-strength testing were employed for different concentrations of the leaf extract admixture in duplicates of steel-reinforced concrete specimens, partially immersed in the corrosive-medium. Analyses of the experimental test-results according to specification ASTM G16-95 R04 showed that Morinda lucida leaf-extract combined highly-efficient corrosion inhibition, 84.82r7.76% Ș 95.64r1.50%, with good compressive-strength improvements in their admixed steel-reinforced concretes. These bear implications for corrosion-protection of wind-energy structures in saline/marine environments.
