The research team from Iowa State University said that if testing of the snow melting concrete is successful, the technology could also be used in and around gates for the airport ground-handling equipment and employee activity, as well as in front of the terminal for passengers.
The slabs, which can be controlled by smartphone, are 4.5m by 4.1m concrete and are formed of two layers. The bottom stratum is 100mm of regular concrete, and the top layer is 890mm layer is made from the conductive material. Between the layers are 12 electrodes, six per slab, running the width of each slab to create the heat.
