TY - CONF A1 - Ebell, Gino T1 - Galvanic Anode systems in Concrete structures and their performance part 1 N2 - Corrosion of reinforcement is one of the major reasons in questioning the sturdiness of building structures. The application of cathodic protection techniques plays a big role in controlling the corrosion process to ensure a longer service life of building structures. This systematic study compares the efficiency and durability of various discrete galvanic zinc anode systems available in the current market using different criteria for measuring efficiencies such as potential measurements, electrolyte resistance measurements and several polarization methods to determine the polarizability of the anodes. Results to validate the performance of long-time exposure of discrete zinc anodes in the concrete medium are already shown in 2021. Now the results of analyzing the phase boundary between mortar and anodes by using 3D computer tomography are shown, as also the field application at large-scale specimens where the potential distribution and the current were investigated.
