What is CP?
Cathodic protection prevents corrosion by the application of a current on the metal structure-Positive charged anode forces steel to be negatively charged (become a cathode)
Typical Areas of Concern
- Coastal structures (balconies & Walkways)
- parking Garages, Highways, Bridges
- Steel Frames Historic Masonry Structures
- Sea walls and other marine Structures
- Industrial Facilities
The Corrosion Process
- Once the chllorides penetrate to the reinforcing steel, the concrete's high pH no longer passivates the steel.
- A typical galvanic corrosion cell forms and corrosion can occur quite quickly
Corrosion Process
- Normal conctere has a very high pH(Alkalinity) and this provides protection against corrosion of the embeddded steel (passivation)
- Chlorides and other salts, over time can penetrate the Corrosive Enviornment De-icing salts, coastal cloride despostion, heat, humidity, CO2, F/T
