Abstract

La invención se refiere a un sistema anódico galvánico para la protección anticorrosión de acero en hormigón. El sistemaanódico galvánico según la invención está constituido por un material anódico galvánico alojado en un electrólito sólido, que está constituido por cinc y sus aleaciones, y está caracterizado por que la superficie disponible galvánicamente es mayor,preferentemente al menos el doble que la superficie geométrica total del ánodo metálico. El sistema anódico galvánico según la invención está caracterizado además por que, durante el trabajo,durante el cual el ánodo se disuelve como ánodo de sacrificio, la superficie anódica activa galvánicamente se reduce insignificantemente, de modo preferente no se reduce hasta al menos un 50 %, en especial un 75 % del tiempo de utilización.
