Fiber-filled concrete overlay in cathodic protection

摘要

Reinforced concrete typically having steel reinforcing bars embedded in the concrete can have valve metal anodes forming a part of a cathodic protection system for the concrete structure. For embedding the anodes to serve in the cathodic protection system there is now used a fiber-filled concrete overlay. Polymeric or ceramic fiber is particularly useful in such overlay. There is now provided not only reduced shrinkage cracking for the overlay itself, but also lower current demand for the cathodic protection system.
