Abstract: An electrolytic restoration of concrete includes an anode positioned at a surface of the concrete to be restored and the communication of a current from the anode to the reinforcing bars in the concrete as a cathode. The anode is in the presence of or carries an electrolyte so that sufficient current is provided temporarily over a sufficient period of time so that ions from the concrete are carried through the concrete and expelled into the electrolyte for extraction. The anode is provided by layer of conductive material which is particulate or fibrous so that it is an amorphous layer which can therefore follow the surface of the concrete. In a horizontal arrangement, the layer can be applied directly onto a felt mat for carrying electrolyte. In a vertical orientation an initial layer of chopped cellulose is wetted and applied onto the vertical surface followed by the same layer carrying carbon powder so that the layer is conductive and forms the anode when connected to metal connector plates buried in the anode layer.

Abstract: Sacrificial anodes for installing in an ionically conductive medium at an installation site containing metal requiring cathodic protection are formed by locating anode cores in a tray having dividing members defining a row of side by side chambers with each chamber containing a respective one of the anode cores and casting into the receptacle a covering mortar for the anode cores with each anode core receiving a coating at least partly surrounding the anode core with the connecting wire exposed. The mortar is cast to form frangible bridges between each anode and the next. The trays are stacked and transported to the site where the installer separates and individually installs the anodes into the medium.
