Cathodic Protection of Two Concrete Bridge Decks Using Titanium-mesh Anodes: Interim Report

Report No: 91-IR5

Published in 1991

About the report:

Expanded titanium mesh with a layer of precious metal oxides sintered around it has recently been introduced to fulfill the need for a durable anode in the cathodic protection (CP) of concrete bridge decks. In addition to being resistant to chemical attack, the titanium mesh (1) provides relatively high electrical redundancy, (2) requires minimal labor to install, and (3) is compatible with concrete overlays. To provide the Virginia Department of Transportation with an opportunity to observe and gain experience with the use of this promising type of anode, plans were formulated to use titanium mesh from three different manufacturers in a CP system as part of the rehabilitation of two existing concrete bridge decks that had salt-induced concrete deterioration.
