Truck-weighing stations on highways could become a thing of the past as a result of a new application for "smart concrete" developed by University of Buffalo engineers. Smart concrete is concrete that has been reinforced with short carbon fibers. The electrical resistance of concrete is modified with a very small amount of fibers and changes in response to strain or stress. The concrete acts as a sensor, because the carbon fibers are much more electrically conductive than the concrete mix. By calibrating the smart concrete prior to the testing, the researchers were able to determine the relationship between resistance and weight. Other applications for smart concrete include using it to sense real-time vibrations of bridges, other highway structures, or buildings for use in dampening vibrations, or for earthquake mitigation.
