This work provides a thorough evaluation of high strength concrete (HSC) constructions augmented with hybrid fibers, emphasizing their mechanical properties and structural performance. High-strength concrete, characterized by a compressive strength of 55 MPa or greater, is extensively employed in contemporary construction, especially in skyscrapers, owing to its capacity to reduce column dimensions. Nonetheless, conventional HSC demonstrates deficiencies, such as inadequate tensile strength and ductility, which may jeopardize structural integrity. The integration of fibers into concrete mixtures has been increasingly prevalent during the past decade to tackle these issues. Recent research has investigated the utilization of diverse fiber types in hybrid combinations to enhance various performance attributes of HSC. This review consolidates research findings from 2021 onwards, emphasizing the role of hybrid fibers in improving the mechanical properties of high-strength concrete. The paper examines the ramifications of these advancements for future research and practical applications, highlighting the necessity for additional exploration of fiber interactions, performance assessments under varied conditions, and the establishment of standardized protocols for the utilization of hybrid fibers in construction. This review seeks to further the development of concrete technology and its utilization in high-performance constructions.
