Aplicación de protección catódica en el laboratorio a los morteros de escoria activada alcalinamente y al Portland ordinario sometidos a un ambiente marino

this paper analyzes the electrochemical response of the corrosive phenomenon caused by the entry of the chloride ion and, later, with the application of cathodic protection on steel embedded in mortar activated slag (aas) and ordinary type i portland (opc). the electrochemical study was performed by using half-cell potential, lpr and eis. it was found that activated slag mortars were significantly activated thus improving the corrosion resistance of steel when cathodic protection is applied. by using mossbauer spectros-copy, we identified the various types of iron oxides and hydroxides. the study shows that the same types of iron oxides and hydroxides are found on the surfaces of the steel embedded in aas and opc, as well as the corrosion products (magnetite {fe3o4}, wüstite {fe2+o}) y goethite (fe3 + o{oh}).
