In his work to advance the use of new and improved materials in construction engineering, Barzin Mobasher, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, has been overseeing the application of fiber-reinforced concrete in the repair and extension of the Phoenix light rail system. While the overall costs of using the reinforced concrete can be high, the material enables significant savings over time in several ways, including by eliminating the need for conventional rebar material. Mobasher says the use of the fibers in concrete has made the construction process easier and faster, exceeding his initial expectations of its advantages.
