Ultra-high-performance fiber reinforced concrete review: constituents, properties, and applications

Ultra-high-performance fiber reinforced concrete (UHPFRC) is an advanced cementitious composite material that integrates a high-performance concrete matrix and fiber reinforcement. This review paper provides an overview of the constituents, properties, and real-world applications of UHPFRC. It covers the critical stages of UHPFRC, such as mix design, mixing and curing requirements, mechanical and transport properties, thermal properties, and durability properties. Additionally, the paper examines the potential of UHPFRC for strengthening and modernizing existing civil structures and the challenges that may limit its widespread adoption, including high initial cost, lack of comprehensive design standards, and complexity in mix design. The review also investigates current research focuses and knowledge gaps and explores the potential for cost reduction and optimization of UHPFRC.
