Abstract:
Ultra-high-performance concrete (UHPC) is renowned for its exceptional strength and durability, but the undesirable high material cost due to the considerable expense of reinforcing steel fiber hinders its wide application. The incorporation of more sustainable and light synthetic fibers presents a promising avenue for lowering the price and weight of UHPC while affecting the rheological and hardened behavior of UHPC. This paper conducts a comprehensive review of the key parameters of synthetic fibers, including content, aspect ratio, and surface properties, and their impacts on the fresh properties, mechanical performance, durability, and volume stability of UHPC. Particular emphasis is placed on the early and long-term performance of UHPC. Additionally, the sustainability of UHPC with various types of synthetic fibers is compared. By delving into these aspects, this study aims to furnish a constructive reference for engineers and decision-makers regarding the utilization of synthetic fibers in UHPC to achieve optimal early and long-term performance. © 2025 Elsevier Ltd
