摘要

Hybridization has emerged as a pivotal strategy for enhancing the performance of cementitious composites. Researchers have systematically investigated various combinations, including natural and synthetic fibers, natural fibers alone, synthetic fibers alone, and the incorporation of diverse nano- and micro-fillers into fiber-reinforced matrices, to develop hybrid fiber cementitious composites (HFCCs) for a wide range of applications. Numerous studies have evaluated the performance and usability of HFCCs in civil engineering, highlighting the need for a comprehensive and updated review. This article aims to provide an in-depth overview of recent advancements in HFCCs. It compiles and critically analyzes key findings on the physical, mechanical, and thermal properties of HFCCs, in addition to their fatigue performance and non-destructive evaluation techniques. Moreover, the review investigates the diverse application potentials of HFCCs across civil engineering domains. Finally, the study presents strategic recommendations and outlines future research pathways to address current knowledge gaps and technical limitations in HFCC development. Importantly, this work emphasizes that through hybridization strategies, quantifiable improvements have been achieved, including a 30–60% increase in tensile and flexural strength, thermal resistance enhancement up to 800 °C, and notable improvements in fatigue life and impact resistance when compared to single-fiber-reinforced composites.
