Corrosionpedia - What is a Coal Coke Breeze? - Definition ...

Coal coke breeze is a common backfill material used in cathodic protection. It is a type 1 carbonaceous backfill material. Coal coke breeze backfill has low resistivity and low ash content, and may be treated by the addition of 10% (by weight) commercial grade slaked lime. The fuel used in the iron ore sintering processes is coke breeze.
