Biomolecules as a sustainable protection against corrosion of reinforced carbon steel in concrete
چکیده انگلیسی
The aim of the present study is to evaluate the biomolecules which can be potentially used as an eco-friendly inhibitor of steel corrosion in concrete. Biomolecules used in this study are a new class of compounds produced from bacteria cells. The inhibition effect in simulated concrete pore solution was demonstrated using classical electrochemical measurements, microscope observations and X-ray Photoelectron Spectroscopy (XPS). The decrease in corrosion current density was pronounced after adding 1 g L−1 of product in the simulated concrete pore solution. Linear Polarization tests and Electrochemical Impedance Spectroscopy showed the relatively good inhibition efficiency properties (≈58.6%) of BMs. Moreover, XPS analysis and Scanning Electron Microscopy (SEM) observations shown that this type of biomolecules seems to be a film-forming mixed type inhibitor.
