In the present paper the accuracy of three electrochemical laboratory techniques in order to evaluate the corrosion rate of galvanized rods inmersed in solutions which simulate the pore solution, is commented. The techniques used were: polarization resistance, electrochemical impedance and harmonic analysis. The corrosion intensity values obtained through these techniques were compared with the gravimetric ones. Values of constant B obtained through polarization curves and the harmonic analysis were compared.
