Conductive concrete – an electrifying idea

2016-7-8  So, what is conductive concrete (CC)? Conductive concrete may be defined as a mixture containing a certain amount of electrically conductive components in a regular concrete, designed to enable conduction of electricity. Regular concrete is not electrically conductive. Carbon and steel, in the form of particles and fibres have been used for the conductive components. Geological materials, such as iron ore, may also be used for aggregates in concrete to enhance conductivity.

Today a professor of structural engineering at the University of Nebraska-Lincoln, Chris Tuan first got the idea for conducive concrete while working as a contractor for the Air Force in 1994. Over time, he and several collaborators refined a blend of concrete additives, eventually developing a mixture that made use of pure, lab-synthesized carbon and steel fibers to help the finished material conduct enough electricity
