Zusammenfassung:	The effect of acetate ions on the corrosion of reinforcing steel in chloride environments have been investigated. For this purpose, potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS) and compressive strength techniques were used. In the presence of acetate ions polarization resistance ( R p ) values of reinforced concrete were higher than those without acetate ions. AC impedance spectra revealed the similar results with R p measurements. The compressive strength of concrete specimens containing acetate ions was measured and an increase of 14.7–38.9% was observed.
