By mixing fibers made of steel or comparable composites of materials into concrete, Fulton Schools professor Barzin Mobasher says building concrete structures and using it as a pavement could be more cost-efficient, reduce the carbon footprint of construction projects and provide significantly higher resiliency to everything from normal wear and tear over time to earthquakes. Mobasher has been leading research to develop this fiber-reinforced concrete for more than a decade and is starting to see it attract contractors’ interest. The material was recently used on a section of the Phoenix metro area light rail line.
