Electrically conductive high-carbon concrete (HCC) is being developed and could potentially be used for many new technological advances. Carbon from high-carbon fly ash and spent carbon sorbent—both byproducts of coal combustion in modern power plants—make HCC a conductor. Initial HCC applications have included low-cost grounding for lightning-vulnerable structures, but a much wider range of use is envisioned, including electrical shielding, self-deicing bridges, induction-charging of electric vehicles, and pavements that function as storage batteries. This article explores some of these possibilities.
