Galvanic protection systems utilize dissimilar metals to provide protection to embedded reinforcing steel. When two metals are coupled together in an electrolyte, the metal with the higher potential for corrosion (more electronegative) will corrode in preference to the more noble metal. In the case of concrete, zinc is used to provide galvanic protection to the steel. This type of system does not require on-going monitoring and is suitable for conventionally reinforced and prestressed/post-tensioned concrete.

Vector Galvashield® CC
Embedded Galvanic Anode for Corrosion Control

Vector Galvashield CC embedded galvanic anodes are used to control on-going corrosion and to prevent the initiation of new corrosion activity in concrete structures. Galvashield CC anodes consist of a sacrificial zinc core that is activated by the surrounding specially formulated precast cementitious mortar. The cylindrical anode, available in a variety of standard sizes, is quickly and easily installed into concrete that is mechanically sound but has on-going corrosion activity. Once installed, the zinc core corrodes preferentially to the surrounding rebar, thereby providing galvanic corrosion control to the adjacent reinforcing steel. Custom size anodes are available for specifi c project needs.

Applications:

  • Balconies
  • Columns and beams
  • Bridge decks
  • Parking garages
  • Piers and wharfs
  • Prestressed concrete
  • Post-tensioning anchors

    • Features and Benefits

  		•  Proven Technology - supported by independent test program.
  		•  Focused protection - discrete anodes can be installed to provide corrosion protection in areas with high corrosion potentials or active corrosion.
  		•  Economical - save money by only protecting the remaining chloride-contaminated (unrepaired) areas.
  		•  Versatile - effective in chloride-contaminated and carbonated concrete. Can be used for both conventionally reinforced and prestressed or post-tensioned concrete.
  		•  User friendly - installation is quick and easy.
  		•  Low maintenance - requires no external power source or system monitoring.
  		•  Measurable - anode performance can be easily monitored if required.
  		•  Long lasting - 10 to 20 year service life reduces the need for future repairs.
