Conductive concrete can de-ice itself

The material is made by adding a small amount of steel shavings and carbon particles to the concrete mix, making it conductive enough to carry an electrical charge. It is due to be tested by the FAA next March and if successful, will potentially be used at airports, preventing the areas used by luggage, food and fuel carts from freezing over. A similar material is already used nearby on the Roca Spur Bridge.
