Galvanic corrosion protection of steel in concrete with a zinc mesh anode embedded into a solid electrolyte (EZA)

A galvanic zinc anode system, composed of a zinc mesh embedded into a proprietary matrix that solidifies into an electrolyte embedded into a solid matrix with ion exchange properties, was developed by CAS. The solid matrix of the embedded zinc anode system (EZA) is based on a tecto-alumosilicate-binder containing additives that prevent passivation of the zinc anode, assure high and durable galvanic activity of the zinc anode and high and durable adhesion towards the concrete overlay. The efficiency of the galvanic corrosion protection (GCP) of the steel reinforcement with a novel embedded zinc anode (EZA) is evaluated on five types of civil structures – abutment of a road bridge in the Styrian Alps in Austria, concrete abutments of a steel bridge, support-beams for the bearings of four viaducts and balconies of apartment buildings in the Netherlands, and a parking deck in Saas Fee in Switzerland.
