This research investigates the effects of steel (ST) and synthetic (SYN) fibers on workability mechanical properties HPFRC. It also analyzes their influence material’s microstructural characteristics. ST improve tensile strength, fracture toughness, post-cracking performance owing to rigidity, interlocking, robust adhesion with matrix. SYN fibers, conversely, mitigate shrinkage-induced micro-cracking, augment ductility, enhance concrete under dynamic stress while exerting negative workability. Hybrid fiber systems, which include offer synergistic advantages by enhancing management at various scales augmenting ductility energy absorption capability. Scanning electron microscopy (SEM) has been crucial in investigating fiber–matrix interactions, elucidating hydration, crack-bridging mechanisms, interfacial bonding. establish thick zones that facilitate effective transfer, whereas reduce micro-crack formation long-term durability. Nonetheless, deficiencies persist, encompassing optimal hybrid configurations, enduring fiber-reinforced (FRC), sustainable substitutes. Future investigations should examine multi-scale reinforcing techniques, intelligent for structural health assessment, alternatives. The standardization testing methodologies cost–benefit analyses is essential promote industrial deployment. review offers a thorough synthesis existing knowledge, emphasizing advancements potential HPFRC high-performance construction applications. findings development new, durable, resilient systems solving current difficulties.
