Conductive Concrete for Bridge Deck Deicing

 

 

 

 

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, Nebraska, which is located about 15 miles south of Lincoln, NE.  The focus of the early research was to prove concept and feasibility of conductive concrete technology in infrastructure applications.
