Synergistic Corrosion Inhibition of Steel Reinforcement in Concrete: FTIR, Corrosion and Polarization Data for Calcined Clay Pozzolan and Acacia Leaf Extract

This dataset contains Fourier-transform infrared spectroscopy (FTIR) spectra, potentiodynamic polarization curves, and calculated corrosion rates supporting the investigation of synergistic corrosion inhibition of steel reinforcement in concrete using calcined clay pozzolan and Acacia leaf extract. The FTIR data characterize the functional groups and chemical interactions of the inhibitors and their admixtures; the polarization curves provide electrochemical parameters including corrosion potential (Ecorr) and corrosion current density (icorr); and the corrosion rates (mm/year) quantify inhibition efficiency, demonstrating the synergistic effect of the combined inhibitors. All data are organized in Excel files and and DPT formats.
