Cathodic Protection of Concrete Bridge Decks Using Titanium-Mesh Anodes

摘要

Anodes are a critical component of cathodic protection systems. A continuousresearch effort in Virginia is being aimed at searching for the most suitable anode for use in cathodic protection of the various types of concrete bridge components that are exposed to intrusion by chloride ions. As part of this effort, three different catalyzed titanium mesh anodes were tested, side by side, in a cathodic protection system that was designed and constructed (in conjunction with the rehabilitation of several concrete deck spans) to prevent further reinforcement corrosion-related damage to these structures. The purpose of this study was to determine whether this type of new anode is suitable for application in bridge decks, and if any of the three meash anodes tested in this study excels over the other.
