Performance of Eco-Fiber-Reinforced Concrete for Bridge Construction and Rehabilitation

This research project aims to evaluate the performance of low-shrinkage fiber-reinforced concrete (FRC) used in the construction and rehabilitation of transportation structures. This research is an extension of projects entitled “Enhance performance of fiber-reinforced concrete with adapted rheology” and “Performance of fiber-reinforced self-consolidating concrete (FR-SCC) for repair of bridge sub-structures and fiber-reinforced super-workable concrete (FR-SWC) for infrastructure construction” that were supported by the RE-CAST UTC. To develop Eco-FRC, alternative binder materials will be used to replace Portland cement or over 50% alternative supplementary cementitious materials (SCMs) will be used in FRC. Further work is needed to evaluate the effect of key parameters, such as alternative SCMs, eco-binders, and fiber type on fresh and hardened performance of the Eco-FRC mixture. In addition, laboratory investigations will be conducted to validate the performance of these novel materials under various field conditions, including marine and frost conditions.
