Degradations by Corrosion of Steel Rebar Reinforced Concrete Structures 3.Contributions to Study of Physical Degradation of Reinforced Concrete Caused by Stray Currents

摘要

In order to study the degradation mechanisms of concrete steel structures under the influence of stray currents.The study 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.
