MESH ANODE AND MESH SEPARATOR FOR USE WITH STEEL-REINFORCED CONCRETE

摘要

MESH ANODE AND MESH SEPARATOR FOR USE WITH STEEL-REINFORCED CONCRETE An insulating separator along with an anode for cathodically-protected steel-reinforced concrete is embedded in an ion-conductive overlay on a concrete structure. The insulating separator is at least one sheet of polymer mesh. The anode is at least one sheet of highly expanded valve metal in mesh form. Both the polymer mesh and the anode mesh comprise mesh having a pattern of voids defined by a network of strands connected at a multiplicity of nodes. The surface of the valve metal mesh carries an electrochemically active coating. The insulating polymer mesh separator overlays the concrete structure surface and separates the anode mesh from such surface. Both the polymer mesh and the anode mesh are embedded in the ion-conductive overlay. At least one current distribution member can be fastened to the valve metal mesh.
