Galvanic (sacrificial) anodes for cathodic protection

Specifies the requirements for galvanic (sacrificial) anodes for use in the cathodic protection of metals against corrosion. It specifies the composition of suitable alloys for magnesium, zinc and aluminium anodes and gives details of shape and design features of some commonly used anodes. It also includes details of backfill composition and properties, for buried magnesium and zinc anodes.
