Zusammenfassung:	The relationship between corrosion potential thermodynamics and polarization resistance (electrode kinetics) was analyzed. The influence of cement replacement materials (fly ash and slag) on corrosion resistance of steel in concrete in 3.5% NaCl solution was also investigated by corrosion potential and polarization resistance measurements. Replacement of cement by 10% fly ash shows improved corrosion resistance by reinforcing steel in concrete while concrete with 15 and 30% replacement of cement with slag results in a significant reduction in corrosion resistance of reinforcing steel.
