摘要

To enhance the performance of cement-based materials, researchers integrate fibers into the cement matrix, creating fiber-reinforced cement-based composites. However, the intrinsic physical properties of the fibers can significantly limit their practical applications. To address this issue, researchers have developed various fiber coating techniques to improve their effectiveness in cement-based composites. This article reviews recent advancements in coating technologies for fiber-reinforced cement composites. It begins by introducing the preparation and characterization methods of different fibers, detailing how these processes affect fiber properties. The article then summarizes the impact of fiber coatings on the fiber/cement interface and the resulting microstructure of the composites. Analyze the effects of different treatments by comparing single fiber pull-out tests and the mechanical properties of treated versus untreated fibers. Finally, the main challenges and future prospects in the field are discussed, with the goal of providing constructive ideas and guidance to support ongoing and future research in fiber-reinforced cement composites.
