Özet

The effect of polyvinylpyrrolidone (PVP) on the corrosion resistance of steel reinforced concrete was assessed by measuring the corrosion potential, linear polarization resistance and AC impedance during 60 days immersion in NaCl and NaCl + PVP Solutions, Polarization resistance (R-p) values of PVP added reinforced concrete were much higher than those without PVP. The relationship between corrosion potential and linear polarization resistance was analysed. Results from corrosion potential measurements were well comparable with the linear polarization resistance data, AC impedance spectra revealed that the resistance of PVP mixed electrodes was also quite higher than the other electrodes. The mechanical properties of concrete were measured. It wits observed that the compressive strength of concrete had increased approximately 44% in the specimens containing PVP. (c) 2005 Elsevier Ltd.
