Sika® FerroGard®-720 Reba

Sika FerroGard-720 Reba is a discrete sacrificial anode applied to reinforcing steel
in new concrete structures exposed to attack by chloride salts.


Reinforced concrete is a porous material and as a result, exposure to chloride salts
can lead to extensive chloride diffusion in to the concrete cover and subsequent
attack on the encased reinforcing steel. This effect is accelerated at higher
temperatures.


To counter potential chloride attack, sacrificial anodes can be placed in susceptible
areas.


Sika FerroGard-720 Reba anodes corrode preferentially to the surrounding steel,
protecting it from further corrosion damage.

Sika® FerroGard®-710 Reba

Sika FerroGard-710 Reba is a discrete sacrificial anode applied to patch repairs on
reinforced concrete structures which are corroding as a result of chloride ingress or
concrete carbonation.


Many structures suffer corrosion damage due to the incipient anode effect following
concrete patch repairs. Although the fresh mortar in patch repairs halts corrosion of
the steel within, it does not deal with chloride contaminated concrete outside the
patch repair which is the cause of the corrosion. This leads to further corrosion
damage at the periphery of the repair.


Sika FerroGard-710 Reba anodes redress the electrochemical imbalance induced
through removal of the corrosion process from steel in the patch. Sika FerroGard-
710 Reba anodes corrode preferentially to the surrounding steel, protecting it from
further corrosion damage.
