Abstract
A sacrificial galvanic anode, an anodic assembly including the sacrificial anode, and a method of cathodically protecting steel reinforcement in concrete structures from corrosion is provided. The sacrificial galvanic anode comprises at least one sacrificial metal helical coil. The galvanic anode is easily fabricated and occupies a minimum volume within a steel reinforced concrete structure while providing maximum surface area for sacrificial corrosion.
