【 摘 要 】

Conventional glass fiber-reinforced concrete (GFRC) has wide applications in high-rise buildings, bridges, and renovation works. In this study, ultra-high-strength glass fiber reinforced concrete (UHS-GFRC) mixtures were developed to minimize the size of the structural members. The percentage of glass fiber was varied as 0%, 0.03%, 0.06%, 0.09%, and 0.12%. In this investigation, ten beams were cast and tested, with two span-to-effective-depth (a/d) ratios of 1.6 and 2. All the tested specimens attained their respective strengths; however, the strength values varied. Specifically, the specimens reinforced with 0.09% and 0.06% of glass fiber exhibited the highest flexural and shear strengths, respectively. The results obtained in this study can be utilized to select optimum mixtures of UHS-GFRC under satisfying service conditions.
