Nebraska bridge uses self-heating concrete to melt snow and ice in winter

A bridge in Nebraska has been fitted with 52 slabs of electrically conductive concrete capable of melting snow and ice during winter storms. The technology was developed by University of Nebraska-Lincoln professor Chris Tuan and works by embedding steel shavings and carbon particles into concrete to conduct electricity and generate heat. The innovation could significantly reduce reliance on de-icing chemicals at bridges, airport tarmacs, and intersections. Beyond road infrastructure, the technology holds potential for widespread use across various surfaces prone to dangerous icing conditions.
