Conductive Concrete for Ice-Free Roadways
If you’re tired of shoveling snow, conductive concrete could be your savior. Researchers at the University of Nebraska-Lincoln engineered concrete that melts ice.
The energized concrete can be used on driveways, roadways, and bridges. Since magnetite-rich aggregates are blended into the specially-designed mix, it can also be used for military applications in electromagnetic shielding.
For DIY-enthusiasts, it may seem tempting to whip up a batch of homebrewed conductive-concrete mix. But, it’s not as simple as plunging a steel rod into concrete and juicing it up with a power source.
Firstly, a precise formula of conductive components—steel fibers, steel shavings, and carbon particles—is added to conventional concrete mix. Then,…[Read more]
