Abstract

Due to its excellent mechanical properties, ultra-high-performance fiber reinforced Concrete (UHPFRC) has attracted the attention of researchers and engineers since its introduction in the mid 1990s. Indeed, the application of UHPFRC in engineering has significantly reduced the self-weights of structures and improved their spans, strengths, and durability. Furthermore, UHPFRC materials exhibit increased energy absorption making them excellent for the protection of structures against blast and impact. Despite these superior properties, UHPFRC materials raise the production cost and increase carbon footprint, compared to their conventional Concrete and even High-Performance Concrete counterparts. This study presents the results of an extended experimental work, emphasized on the development of an optimized UHPFRC mix that considers beyond mechanical, physical and durability properties, the ability of an UHPFRC material to resist impact. To achieve this, numerous mixtures of UHPFRC have been prepared while a parametric analysis was conducted to determine the critical parameters affecting the performance of each UHPFRC mix, therefore the specific experimental results and overall outcomes are presented.
