ABSTRACT:
Mixed-metal-oxide (MMO) coated precious-metal tape is installed directly on concrete surfaces using an electrically conductive adhesive, thereby obviating the need for slots, holes, cementitious grout or additional concrete. The electrically conductive adhesive is preferably formed by disposing mixed-metal-oxide (MMO) coated precious-metal particles in an adhesive layer. The tape anodes may be installed on the concrete surfaces including a shallow concrete cover or congested reinforcing steel without developing an electrical short circuit between the anode and the reinforcing steel. Overall the invention provides for quick and low cost installation on many concrete structures. Interconnections between the tape anodes and bare metal distribution elements may be made with conductive adhesive or spot welding.
