Ultra-High-Performance Concrete (UHPC): A State-of-the-Art Review

Materials (Basel). 2022 Jun 10;15(12):4131. doi: 10.3390/ma15124131.

Abstract

The interest of researchers in UHPC has increased over the past decade. It is crucial to understand the structural behavior of reinforced UHPC (R/UHPC) components under various loading conditions before they can be used as a replacement for conventional concrete. Although several studies on ultra-high-performance concrete (UHPC) have been conducted, the knowledge is scattered, and no one can easily judge the performance and methodology of UPHC. Therefore, the purpose of this study was to review the research studies already carried out on UHPC. The review focuses on the materials' physical and chemical composition, mechanical and durability characteristics, fire resistance, and environmental benefits of UHPC. Design considerations for effectively utilizing UHPC in structural elements are also presented. The best UHPFRC mixture is obtainable with a steel fiber content of 2-3% and a water-to-cement ratio of 0.2-0.3. The review also discusses the essentials recommendation for future research on UHPC.
