Rezumat:

With the aim to study the degradation mechanisms of concrete steel structures under the influence of stray currents, we have determined, on cylindrical samples, the evolution in time of volumic electrical resistance and breakage resistance, too. The determinations were performed comparatively, on control samples and samples affected by the constraint of polarization currents in A.C. and D.C., in 1%NaCl a queans solution
