In this paper is presented influence way of preparing steel reinforcement on rate of corrosion steel reinforcement in cement mortar. Reinforcements were prepared mechanically and chemically. Testing of corrosion of reinforcing steel in cement mortar is executing on the measuring device which consists of an electrochemical cell and potentiostat/galvanostat EG & G PARC, model 263A. Electrolyte used in this case is saturation solution Ca(OH)2. Preparation of working electrode and experiment are according to standard JUS U.M1.044. Results of experiments are presented in form of anode polarization curves of steel bars in concrete, using linear voltmeter method. Evaluation of the results of testing the intensity of corrosion is carried out according to the procedure prescribed by the standard JUS U.M1.035. The results show that the corrosion rate is significantly higher on chemically prepared steel reinforcement.
