By enabling radiant heating in pavements, nanocarbon cement could be used to de-ice pavements without road salt
Nanocarbon black electrifies concrete, turns it into a heat radiator Concrete is an electrical insulator -- but a sprinkle of nanocarbon allows electrons to flow. MIT CSHub postdocs Nicolas Chanut and Nancy Soliman hold two of their conductive cement samples. Credit: Andrew Logan. Concrete is such an indispensable construction material that humans invented it twice, more than a thousand years apart. The merit of concrete in supercharging our current infrastructure cannot be overstated, but a group of researchers at MIT still found a way to spice things up. Normally, concrete is an electrical...
