Galvashield® CC - Concrete Corrosion Control

Galvashield® CC embedded galvanic anodes are installed into drilled holes to mitigate active corrosion.   The anode units are alkali-activated with an internal pH of 14 or greater to keep the zinc active over the life of the anode and are not corrosive to reinforcing steel. Once installed, the zinc anode corrodes preferentially to the adjacent reinforcing steel to provide galvanic corrosion control.

Galvashield CC anodes are classified as Type 2AC Anodes – alkali-activated anodes for corrosion control in sound concrete.  A typical use is to install anodes into “hot spots” as determined by corrosion potential surveys.
