Cathodic prevention was implemented with commercial Zn bulk anodes on laboratory columns simulating a reinforced concrete marine system. Two computational models of these laboratory columns were implemented. The results obtained from both models were in reasonable agreement with the experimental observations. One of the models was used to predict cathodic prevention throwing power on field scale structures, as a step towards field application. These predictions suggest that with an immersed anode useful levels of cathodic
prevention may be reasonably expected, even under conservative assumptions, in the area immediately above high tide where conditions are otherwise very severe.
