A bridge structure exposed to salt can expect corrosion of the embedded steel during its service life. Cathodic Protection (CP) has proven itself as the only permanent repair of existing corroded steel reinforced concrete. Therefore, CP must not be considered separately, but as a part of a complete rehabilitation program.

Goodier, Chris Atkins, Jim Preston. Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the. The majority of bridge structures in Minnesota are constructed of reinforced concrete. The service life of a reinforced concrete bridge is significantly influenced, and often controlled, by the extent of deterioration that develops in the bridge deck and substructure over time.
Deterioration typically manifests as a result of exterior exposure. Cathodic Protection for Life Extension of Existing Reinforced Concrete Bridge Elements NCHRP Synthesis AASHTO Reference Book - AASHTO Transportation Glossary - 4th Edition Bituminous Materials and Mixtures - No.

Complete cathodic protection in a sand with active IB could be achieved at the off-potentials more negative than V (Cu/CuSO4). (2) Cathodic protection in a sand with active IB was mainly brought about by the decrease in IB activity due to the environmental changes as pH shift into alkaline and aerobic shift into anaerobic.

Durability of reinforced concrete structures; steel corrosion. Durability of reinforced concrete structures can be defined as the ability of a structure or component to withstand the design environment over the design life, without undue loss of serviceability or need for major by: 4.
When it comes to parking garages, durability is key, as they are often located in busy metro areas where closure, repair, or reconstruction can be disruptive. Time, labor, and material costs for renovation are also prohibitive.
These structures are generally made from reinforced cast-in-place or precast concrete, making corrosion one of the most common. Corrosion Prevention and Control 1. Corrosion Prevention and Control: A Program Management Guide for Selecting Materials Benjamin D.
