Prolonged corrosion inhibition response of sodium lauryl sulphate (SLS) on steel reinforcement in contaminated concrete was investigated by gravimetric method and electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy. Using half cell potential measurements probability of steel reinforcement corrosion was monitored for a period of 480 days. FT-IR spectroscopic analysis of the corroded products deposited on the steel reinforcement revealed the mechanism of corrosion inhibition. Modification in the surface morphology of steel specimens in the concrete was examined by optical microscopy. During the period of investigation (480 days), SLS showed appreciable corrosion inhibition efficiency on the steel reinforcement in concrete.

Corrosion inhibition of concrete steel-reinforcement in 3.5% NaCl, simulating saline/marine environment, by the leaf extract ofRhizophora mangleL. was studied in this paper. For this, duplicated specimens of steel-reinforced concrete slabs, admixed with different concentrations of the leaf extract, were immersed in the corrosive test-medium. Analyses, as per ASTM G16-95 R04, of the electrochemical test-results identified 0.0833%Rhizophora mangleL., per weight of cement, with optimal inhibition efficiencyη= 95.73±0.15%. The study established a decrease in inhibition effectiveness as concentration ofRhizophora mangleL. increases.

Surface applied corrosion inhibitors (SACI) are widely used to mitigate the corrosion process of steel reinforcement in concrete. But they remain controversial as to their effectiveness and the ability to compare materials from different manufacturers and technologies. They are applied onto the surface of hardened concrete and penetrate towards the steel reinforcement. This paper discusses the corrosion inhibition performances of a dual-phase corrosion inhibitor and field surveys through corrosion monitoring the selected structures. The efficiency of the corrosion inhibitor is assessed by selected testing procedures in laboratories.
