Sika Ferrogard 650 - 60g of Zinc, Embedded Galvanic Anodes, 30 Per Box

Sika FerroGard-650 is a zinc-based discrete sacrificial anode placed inside a concrete repair area in reinforced concrete structures which are corroding as a result of chloride-induced corrosion.

Sika FerroGard-650 anodes are placed along the perimeter of the repair area and fixed to the reinforcement prior to the application of a concrete repair system. The reinforcement outside the repaired area is at the greatest corrosion risk owing to the passive condition of the reinforcement within the repaired area. Sika® FerroGard®-650 anodes corrode preferentially to the surrounding reinforcement offering protection against incipient corrosion damage.

Uses:

• Patch repairs within concrete or along joints between new and existing concrete. Effective in chloride contaminated and carbonated concrete. Used to prevent the “Halo” or “Ring” anode Corrosion effect.

Advantages:

• Anode Mortar Shell - uses proprietary technology that provides excellent transport of reactants to the surface of the zinc anode and corrosion products away from the surface of the zinc, using a chelation process. The encasing mortar will not cause corrosion of reinforcing steel.
• Proven technology – supported by 10+ years of development and testing.
• Cost Effective – lowers Life Cycle Cost of repairs.
• Auto-Corrosion – encasing mortar maintains performance but does not auto- or self-corrode the zinc anode.
• Ease of Installation – uses standard attachment methods known to the industry.
• Self-Powered / Self Regulating – creates own protective current that adjusts to demand.
• Maintenance Free – requires no monitoring or maintenance.
• Safe to Use – protect conventional and pre-stressed / post-tension reinforcing steel; moderate pH safe to handle without PPE.
• Tie Wires – galvanized steel tie wires (annealed) are pre-twisted to form a cradle that accepts reinforcing steel, enables a better electrical contact and extends “throwing power”.
• Service Life – capable of 10+ years of protection depending on design and conditions.
