This paper concerns the polarization tests on steel reinforcement in a solution simulating concrete pore solution. It describes an attempt to evaluate the effect of polarization range measured in an unusual way, that is, around the rebar circumference, and not along its length. Tests were conducted in a three-electrode system by impedance spectroscopy. A working electrode was a steel bar with a diameter of 22 mm, made of reinforcing steel of grade RB500. Cl–/AgCl,Ag electrode was used as a reference electrode, and a counter electrode was made of corrosion-resistant steel sheet. Three geometric parameters of the system: polarization of circumferential range, the counter electrode width and the counter electrode distance from the tested rebar were considered as variables during the tests. A discrete change in the circumferential range of polarization was achieved by decreasing gradually the level of an aqueous solution in a container with electrodes. The container was filled with synthetic pore solution with pH = 13.4, in which passivation of the steel bar was expected. The analysed test results indicated that the counter electrode width could have an impact on the fact that the linear relationship between charge transfer resistance and the polarization range around the rebar circumference was not repeatable.
