This research paper deals with the steel/concrete interface of concrete samples with and without green inhibitor (orange peel extract) and with different two types of superplasticizers (Mapei Dynamon SR 31 and Oxydtron) after an 18 months exposure in aqueous chloride environment. XRD, SEM, and light optical micrograph techniques were applied to investigate the chemical compositions and the spatial distribution of the corrosion products. The experimental results revealed and illustrate that the corrosion products were visible in samples without inhibitor and appeared less noticeable in samples with Mapei Dynamon SR 31 but in the samples with Oxydtron were almost non-existent.
