The present study investigates the mechanical and durability performance of Bendable High-Performance Concrete(BHPC) incorporating Alkali-Resistant Glass Fibers (ARGF) and fly ash as a partial replacement of cement. The primary objectivewas to enhance ductility, crack resistance, and sustainability while maintaining high compressive strength. M50 grade concrete wasdeveloped with varying ARGF contents (1.5%, 2.0%, and 2.5% by volume) and 30% fly ash replacement. Comprehensiveexperimental tests including workability (slump cone), compressive strength, split tensile strength, flexural strength & ultrasonicpulse velocity (UPV) were conducted. Results revealed that the optimum fiber content was 2.0%, which significantly enhancedcompressive strength (19% higher than control), split tensile strength (32% higher), and flexural strength (30% higher). Thesefindings confirm that BHPC with ARGF and fly ash provides superior mechanical properties and durability, making it suitable forseismic-prone and long-life structures.Keywords: Bendable Concrete, High Performance Concrete, Alkali-Resistant Glass Fiber, Fly Ash, Mechanical Properties,Durability.
