Fast Construction and Repair of Bridge Elements Using Low Carbon Foot Print SCC and UHPC Prefabricated Panels Reinforced with FRP

The service life of concrete infrastructure elements depends on the quality of the cover-crete; outer 50 mm of the concrete. The use of high-performance concrete can indeed prolong service life of the material. However, this material is still prone to cracking. Recently, ultra high-performance concrete (UHPC) has been introduced which has much higher mechanical properties and toughness than HPC. UHPC is typically a micro-mortar reinforced with micro fibers (typically steel fibers) resulting in extremely impermeable and crack-resistant material. Such material can be used to produce precast panels that can be assembled on-site for the construction of bridge vertical elements, such as the construction of girder and bridge pier elements. This project aims at developing UHPC that can be used as a formwork system for cast in-place bridge construction. The proposed units are targeted for bridge construction and use low carbon foot print self-consolidating concrete (SCC) and UHPC prefabricated panels reinforced with fiber-reinforced plastic (FRP) bars. The use of the proposed approach can result in several advantages for the United States transportation infrastructure system, including: (1) design of fast construction and rehabilitation system for transportation infrastructure that can exhibit extended service life; (2) use of environmentally friendly SCC to cast the structural element can provide a rapid construction procedure; (3) notable savings in labor and time by designing a permanent formwork system.
