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.

合成纤维对 UHPC 早期和长期性能的影响:综述
超高性能混凝土 (UHPC) 以其卓越的强度和耐用性而闻名,但由于增强钢纤维的大量费用,令人不快的高材料成本阻碍了其广泛应用。加入更可持续和更轻便的合成纤维为降低 UHPC 的价格和重量提供了一条有前途的途径,同时影响 UHPC 的流变和硬化行为。本文对合成纤维的关键参数进行了全面综述,包括含量、纵横比和表面特性,以及它们对 UHPC 的新鲜性能、机械性能、耐久性和体积稳定性的影响。特别强调 UHPC 的早期和长期性能。此外,还比较了 UHPC 与各种类型合成纤维的可持续性。通过深入研究这些方面,本研究旨在为工程师和决策者在 UHPC 中利用合成纤维以实现最佳的早期和长期性能提供建设性的参考。
