Abstract
The present disclosure relates to a cathodic protection system for inhibiting oxidation of a reinforcing member disposed within a cementitious structure. The system comprises a compact, autonomous battery adapted to mount to the cementitious structure at an open-air location, the battery having a positive terminal and a negative terminal, a conductor adapted to electrically connect the negative terminal of the battery to the reinforcing member of the cementitious structure, an anode jacket constructed of a cementitious material and being adapted to be placed in physical contact with the cementitious structure, and an anode disposed within the anode jacket and being adapted to be positioned proximate to a portion of the reinforcing member disposed within the cementitious structure that is to be cathodically protected, the anode being electrically connected to the positive terminal of the battery.
