The galvanic couple effect decreases a few weeks after performing local repairs, nonetheless, there isfew information on the effect the anodic/cathodic area (aA/aC) ratio has on the magnitude of thegalvanic couple. The selective use of stainless steel represents an alternative to repair concretestructures, but it remains understudied, particularly in tropical marine environments of the Gulf ofMexico. In this paper, the influence of the anodic/cathodic area ratio on the galvanic behavior, beforeand after local repairs, conducted on small beams made of low-quality concrete and 304 stainless steel(SS) bars is analyzed and discussed. Some of the results from this experiment indicate that an aA/aCratio of more than five causes a significant decrease in the galvanic couple of the adjacent areas.
