Nanotechnology researchers convert cement into an electrical conductor

 This new technology, developed and patented by the UA Civil Engineering Department’s Research Group in Multifunctional Concrete Conductors, allows, among other functions, the material to heat up due to the passage of current. “The technology allows buildings’ premises to heat or prevents the formation of ice on infrastructure, such as highways, railways, roads, airstrips and other elements”, lecturer Pedro Garcés, head of research, explains. "To obtain a cementitious compound effective as the heating element, this should have a low resistivity. This is not achieved in conventional concrete because they are poor conductors of electricity. However, this can be achieved by the addition of conductive materials such as, for example, carbonaceous materials”, Pedro Garcés adds.
