Electric Concrete Keeps Runways Clear

Mar-31-17 Researchers have developed an electrified concrete that could help keep airport runways free of ice and snow.

The concrete, created and currently being tested by a team from Iowa State University, is made up of two layers. The top layer is made from a mix of cement, sand and rock combined with one percent carbon fiber, while the bottom layer is made from regular concrete. Between the two layers lies an array of six electrodes wired to a power supply. The electrodes can be controlled by an app, sending a current through the electrically conductive top layer to create enough heat to melt ice and snow and still remain safe to touch.
