Cathodic protection of RC structures - Far more than bridge decks

When the first trials with Cathodic Protection (CP) on reinforced concrete (RC) structures were carried out nearly 30 years ago the main aim was treating steel in bridge decks, suffering from chloride induced corrosion. Various types of anode systems (conductive asphalt, conductive mortars, carbon fibre strips, since the early 1980s titanium...

Experimental study of cathodic protection of concrete from a 30 year old bridge

An experimental study of cathodic protection (CP) was carried out with a conductive primer anode applied to specimens from a concrete bridge. The bridge was demolished after 30 years of service due to severe delaminations and reinforcement corrosion. Four specimens of approximately 1 m2 each were made and characterised by steel potential,...
