Abstract: Cathodic protection of steel in a concrete column in sea water is simplified by providing a pre-assembled unit including a jacket to surround the column carrying a bulk sacrificial anode outside the jacket and optionally an inner sacrificial anode with a cast grout inside the jacket. The jacket can also include a pre-assembled junction box and couplings to connect to the steel. The jacket is attached to the surface of the column at the water line so that the bulk anode is located below the surface of the water. The bulk anode can be formed of aluminum so as to be less toxic in sea water. An activator is applied inside the jacket either as a wicking layer or as a chemical activating material. The jacket can act only as a form work which is then removed after casting of the grout.

Abstract: Cathodic protection of steel in a concrete column in sea water is simplified by providing a pre-assembled unit including a jacket to surround the column carrying a bulk sacrificial anode outside the jacket and optionally an inner sacrificial anode of a zinc mesh or strips on an inside surface. The jacket can also include a pre-assembled junction box and couplings to connect to the steel. The jacket is attached to the surface of the column at the water line so that the bulk anode is located below the surface of the water and supported relative to the concrete surface solely by the connection of the bulk anode to the covering layer. The bulk anode can be formed of aluminum so as to be less toxic in sea water.
