• Abstract In this paper, the total-corrosion behaviour of reinforcing-steel embedment in concrete samples, having Cymbopon citratus ( C. citratus ) leaf-extract admixture, and which were immersed in 3.5% NaCl (a saline/marine simulating environment) is investigated. Electrochemical data of macrocell current measurements were obtained, as an easy to undertake corrosion monitoring technique, from the steel-reinforced concrete specimens, that had been admixed with different concentrations of the C. citratus leaf-extract, before being immersed in the corrosive test-medium. The obtained data were then rendered to prescribed specification from ASTM G109 for the modelling of the total-corrosion prevailing in the reinforcing-steel within the concrete test-samples. Results obtained showed that C. citratus leaf-extract admixture in the concrete samples led to reduction in the total-corrosion of the reinforcing-steel, and, especially, in agreements with previous works where other types of electrochemical monitoring techniques had been employed.
