Barzin Mobasher, a professor for the School of Sustainable Engineering and the Built Environment, is advancing foundational practices in construction engineering by proposing engineers and contractors adopt fiber-reinforced concrete instead of traditional rebar-reinforced concrete. Fiber-reinforced concrete incorporates tiny fibers into the concrete mix, which helps prevent the formation of large cracks that could compromise the structural integrity of the concrete. Recent projects, such as a Metro Phoenix light rail extension, have demonstrated cost and time savings by using fiber-reinforced concrete. Mobasher says the next big step is to get engineers and contractors to integrate fiber-reinforced concrete into their future builds.
