Zinc anodes shall be made from special High Grade Zinc, with suitable alloying additions.
The zinc anodes shall have steel cores. The steel shall be coated with zinc or cadmium to a minimum
thickness of 12.5 microns. Hot-dipped or electro-deposition methods may be used. Either coating shall be
adherent and free from flaking. The coating shall adhere tenaciously to the surface of the base metal.
When the coating is cut or pried into, such as with a stout knife applied with considerable pressure in a
manner tending to remove a portion of the coating, it shall only be possible to remove small particles of
the coating by paring or whittling, and it shall not be possible to peel any portion of the coating so as to
expose the steel.
Any anode must be capable of a sufficient driving voltage to provide the necessary design current output.
Backfill: Bentonite 20% – Commercial grade gypsum 75% – Anhydrous sodium sulfate 5%
