What is the main role of chemical backfill in cathodic protection systems?

To increase structural weight
To enhance conductivity of anodes
To provide insulation against electric currents
To reinforce structural integrity

The correct answer is: To enhance conductivity of anodes

The primary role of chemical backfill in cathodic protection systems is to enhance the conductivity of anodes. This is critical because cathodic protection relies on a conductive environment to effectively protect metal structures from corrosion. By improving the conductivity around the anodes, the backfill material ensures that the electrical current can be more efficiently distributed throughout the soil or medium surrounding the anodes. A well-conductive backfill allows for better current flow, which increases the effectiveness of the cathodic protection system in mitigating corrosion on metallic structures. The chemical composition of the backfill can be tailored to improve ionic conductivity, which is essential for optimal system performance.
