Abstract
This paper studies the corrosion-inhibition and compressive-strength performance of Phyllanthus muellerianus leaf-extract and triethanolamine (C6H15NO3: TEA) on steel-reinforced concretes that were immersed in 3.5% NaCl medium, a saline/marine simulating-environment. Concentrations of the plant-extract and the organic chemical were employed, individually and in synergies, as admixtures in steel-reinforced concrete specimens and corrosion monitoring of corrosion rate by linear-polarisation-resistance was applied before subjecting the samples to compressive-strength testing/analyses. Results showed that Phyllanthus muellerianus outperformed TEA in anticorrosion and compressive-strength effects but the synergies exhibited further improvements on TEA performance on these test-criteria in the steel-reinforced concretes for the saline/marine test-environment.
