A sacrificial cathodic protection system has been designed to provide
corrosion control to the splash area and the submerged portion of rein
forced concrete bridge pilings. The system consists of a two-piece sta
y-in-place fiberglass form with an internal expanded zinc mesh anode.
It is filled with a portland cement-sand mortar to protect the splash
area. The submerged portion of the pile is protected using a standard
zinc bulk anode.
