The present invention relates to a method of and an apparatus ( 20 ) for cathodic protection of reinforced concrete using discrete anodes ( 22 ) in or on the reinforced concrete member ( 14 ) to improve performance and service life of the discrete anodes. The discrete anode ( 22 ) is embedded in a cementitous grout or mortar ( 24 ) to encapsulate the anode ( 22 ) and provide contact to complete the cathodic protection circuit. A lithium salt is added to the cementitous grout or mortar ( 24 ) in an amount of at least about 0.05 gram per cubic centimeter. The lithium salt functions to enhance the performance of the cathodic protection system ( 20 ) by minimizing the deleterious effects of the anode reaction products on the grout or mortar adjacent to the anode and increasing the protective current delivered to the reinforcing steel.
