Corrosion is a naturally occurring phenomenon. To limit the corrosion behavior of rebar steel in concrete (simulated concrete pore solution -SCPS), the use of inhibitors is a significant method. In the present study the following oxyanions were studied as corrosion inhibitors: Potassium permanganate (PP), Sodium molybdate (SM), TriSodium phosphate (TSP), Sodium Potassium Tartrate (SPT), Potassium dichromate (PDC) and Tri Sodium Citrate (TSC). They act as good corrosion inhibitors The mechanistic aspects of corrosion inhibition are based on the results obtained from weight loss method, the pola...

They act as good corrosion inhibitors The mechanistic aspects of corrosion inhibition are based on the results obtained from weight loss method, the polarization study, AC impedance spectra measurements, UV visible absorption spectroscopy, Fluorescence spectroscopy, surface examination techniques like FT-IR spectroscopy, Cyclic Voltammetry, Scanning electron spectroscopy (SEM) and Energy dispersive analysis of X rays (EDAX) and Atomic force microscopy (AFM).The results the weight loss study show that the formulation consisting of 250 ppm of Inhibitor and 50 ppm Zn2+ has greater percentage of corrosion inhibition efficiency (IE), in controlling corrosion of rebar steel immersed in SCPS prepared in well water.
