Sacrificial anode and backfill combination

Abstract

An anode and backfill steel protector combination for inserting into at least one cavity which is mechanically formed in steel reinforced concrete. The anode and the backfill steel protector combination comprises an anode for insertion into the at least one cavity with the anode comprising a sacrificial metal element less noble than steel and a backfill which comprises a viscous and pliable ionically conductive material for insertion into the at least one cavity. The backfill is packaged within a cartridge and the cartridge is a cartridge for use with a cartridge which facilitates injecting the backfill from the cartridge into the at least cavity formed in the concrete. The backfill in a cartridge has a shelf life of at least 2 days.

We claim: 
     
         1 . An anode and backfill steel protector combination for inserting into at least one cavity which is mechanically formed in steel reinforced concrete, the anode and the backfill steel protector combination comprising: an anode for insertion into the at least one cavity with the anode comprising a sacrificial metal element less noble than steel; and a backfill comprising a viscous and pliable ionically conductive material for insertion into the at least one cavity; wherein the backfill is packaged within a cartridge and the cartridge is a cartridge for use with a cartridge which facilitates injecting the backfill from the cartridge into the at least cavity formed in the concrete, and the backfill in a cartridge has a shelf life and the shelf life is at least 2 days. 
     
     
         2 . The anode and backfill steel protector combination as claimed in  claim 1  wherein the shelf life is at least 7 days. 
     
     
         3 . The anode and backfill steel protector combination as claimed in  claim 1  wherein the shelf life is at least 30 days. 
     
     
         4 . The anode and backfill steel protector combination as claimed in  claim 1  wherein a dispenser is included with the combination. 
     
     
         5 . The anode and backfill steel protector combination as claimed in  claim 4  wherein the dispenser is a cartridge gun. 
     
     
         6 . The anode and backfill steel protector combination as claimed in  claim 1  wherein the anode is sized to fit into a cavity which a hole is 50 mm or less in diameter and is 200 mm or less in length. 
     
     
         7 . The anode and backfill steel protector combination as claimed in  claim 1  wherein the anode is sized to fit into a cavity which is a chase 50 mm or less in depth and 30 mm or less in width.
