Durability Study on Ultra-High Performance Fiber-Reinforced Concrete
Ultra-high-performance concrete (UHPC) stands out as a superior alternative to conventional concrete due to its remarkable enhancements in compressive strength, ductility, tensile strength, and overall lifespan. In present research study, we meticulously formulated three trial mixtures, utilizing locally available materials such as cement, ground granulated blast furnace slag (GGBFS), micro-silica fume (MS), M-sand, quartz powder (QP), water, steel fibers, and chemical admixtures. The investigation delved into rheological parameters to assess the fresh concrete's characteristics and compressive, split tensile, and flexural strength to evaluate the attributes of the hardened concrete. The results of this study illuminate a direct correlation between increased binder content and heightened compressive strength. Additionally, the combination of a low water-to-cement (w/c) ratio, coupled with optimal particle packing, substantially enhances UHPC's durability by fortifying its resistance against moisture infiltration and deleterious ions like chlorides and sulfates. Microstructural analysis unveiled the formation of crucial compounds such as calcium–silicate–hydrate (C–S–H), calcium hydroxide (CH), ettringite, and a resilient interfacial zone characterized by a tightly knit fiber matrix. These findings underscore the promise of UHPC as a viable solution for critical applications where structural integrity and longevity are of paramount concern. In conclusion, this study sheds light on the transformative potential of UHPC, demonstrating its ability to bolster structural performance, mitigate environmental degradation, and extend the service life of concrete structures.
