Conductive concrete is a cementitious
admixture containing electrically conductive components to attain stable and
high electrical conductivity. Due
to its electrical resistance and impedance, a thin conductive concrete overlay
can generate enough heat to prevent ice formation on a bridge deck when
connected to a power source.
In
1998, Yehia and Tuan
developed the first generation conductive concrete mixtures. This technology was successfully implemented in a
demonstration project at Roca,
