Properties of Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC) -A Review Paper

摘要

This study aims to review the research studies available in literature that examines the mechanical properties and optimum mixing ratios of ultra-high performance fiber-reinforced concretes (UHPFRCs). In addition to a comparison between mechanical properties of UHPFRC, high-performance concrete (HPC), and normal strength concrete (NSC). The studies included in this review were compiled under different headings and explained concisely. Subsequently, the best UHPFRC mixture was determined to be obtainable with 2% to 3% steel fiber content and a water/cement ratio of <0.2. Additionally, the UHPFRCs that were subjected to curing at 90 °C for 28 days yielded compressive, tensile, and flexural strengths that were 49% better than the samples cured at 20 °C. The review elucidates the key points of producing the best UHPFRC material for future applications.
