Existing corrosion protection methods (epoxy and zinc coatings, cathodic protection, stainless steel) for reinforced concrete structures are efficient, but in most cases are very expensive or have a short service life. This paper describes some new combined corrosion protection methods, which utilize cathodic protection together with other techniques, which decrease the corrosivity of the environment surrounding the reinforcing steel.
Keywords: reinforced concrete, protection, cathodic, coatings, service life, cost.
