Its widely used as carbonaceous backfill for enhancing the performance of the impressed current foundation. The petroleum coke breeze backfill around the anode makes the anode current be exhausted from the greatly increased surface, thus to reduce the anode resistance and consumption, thereby achieving cathodic protection, and greatly reducing the corrosion rate of the metal pipelines and components embedded in soils. As the backfill, the petroleum coke
breeze is not only featured in low resistance, but also preferable for air exhausting from soil.
