InvestigatingSolanum AethiopicumLeaf-Extract and Sodium-Dichromate Effects on Steel-Rebar Corrosion Insaline/Marine Simulating-Environment: Implications on Sustainable Alternative for Environmentally-Hazardous Inhibitor
Engineering Solutions for Sustainability, 2015Co-Authors: Joshua Olusegun Okeniyi, Adebanji Samuel Ogbiye, Olubanke Olujoke Ogunlana, Elizabeth Toyin OkeniyiAbstract:This paper investigates Solanum aethiopicum leaf-extract and the well-known but environmentally-hazardous sodium-dichromate inhibitor effects on concrete steel-Rebar Corrosion in 3.5% NaCl medium (simulating saline/marine environment). Different equal-concentration models (wt% cement) of the natural-plant leaf-extract and of sodium-dichromate were admixed in steel-reinforced concrete slabs from which electrochemical test-measurements were obtained for comparing admixture performance. Test-results, analyzed as per ASTM G16-95 R04, showed that only the 0.083% sodium-dichromate admixture outperformed the 0.083% Solanum aethiopicum leaf-extract in Corrosion-inhibition effectiveness. The other natural-plant leaf-extract exhibited better inhibition-efficiency performance than their equal-concentration models of sodium-dichromate. The 0.25% Solanum aethiopicum leaf-extract exhibited optimal performance, η = 98.28%, at inhibiting steel-Rebar Corrosion among the also effective different concentrations of the plant-extract and of sodium-dichromate admixtures employed. These and phytochemical test-results bare indications that Solanum aethiopicum leaf-extract is a suitable, sustainable and eco-friendly alternative for the environmentally-hazardous sodium-dichromate inhibitor of steel-Rebar Corrosion in concrete designed for saline/marine environments. © Copyright 2015 by The Minerals, Metals & Materials Society.

Rebar Corrosion in carbonated concrete exposed to variable humidity conditions. Interpretation of Tuutti’s curve
Corrosion Science, 2009Co-Authors: Patrick Dangla, W. DridiAbstract:This paper deals with the modelling of the Rebar Corrosion kinetics in unsaturated concrete cover. The concrete is assumed carbonated resulting in an active Corrosion of steel. The Corrosion kinetics is coupled with the ionic transport processes. Free Corrosion in different concretes is studied in terms of ambient relative humidity. The numerical results obtained by the finite volume method are discussed and compared with a reported experiment performed on a carbonated concrete.

inhibition of steel Rebar Corrosion in industrial microbial simulating environment by morinda lucida
Solid State Phenomena, 2015Co-Authors: Joshua Olusegun Okeniyi, Cleophas Akintoye Loto, Abimbola Patricia Idowu PopoolaAbstract:This paper studies inhibition of steel-Rebar Corrosion in concrete immersed in 0.5 M H2SO4, simulating industrial/microbial environment by the leaf extract of Morinda lucida. Electrochemical monitoring methods were employed for testing different concentrations of the leaf extract admixed in duplicated specimens of steel-reinforced concrete slabs immersed in the acidic test-system. Statistical analyses as per ASTM G16-95 R04 of the experimental results showed that effectiveness of Morinda lucida at inhibiting concrete steel-Rebar Corrosion increased with the concentration of the admixture. 0.4167% Morinda lucida, per weight of cement, was identified with optimum inhibition efficiency η = 98.78±0.34% followed in effectiveness by 0.3333% Morinda lucida with η = 93.20±1.76% at inhibiting steel-Rebar Corrosion in the corrosive test-environment.
