A special blend of concrete that can de-ice roads and pavements without the need for chemicals uses electricity to melt away snow and sleet – and it could be coming to an airport near you soon.
The conductive concrete, developed by researchers at the University of Nebraska-Lincoln, is for the most part the same as regular concrete, but 20 percent of its ingredients aren’t exactly standard: steel shavings and carbon particles, which give the mix enough conductivity that it can melt ice and snow while remaining safe to the touch.
Designed by civil engineer Chris Tuan, the conductive concrete is currently being assessed by the US Federal Aviation Administration (FAA), which is looking into the possibilities of incorporating the snow-melting surface into the tarmac of at least one major airport as part of a trial.
