Plant fibers (PFs) have been increasingly employed in cement-based gel composites (CCs) on account of their excellent mechanical properties, toughness and sustainability. Researchers have engaged in a lot of studies on plant fiber-reinforced cement-based gel composites (PFRCCs). Based on these studies, the chemical components and mechanical characteristics of PFs are summed up in this review. In addition, the modification methods for matrices and PFs are also discussed. The mechanical properties of PFRCCs, including static and dynamic properties, are reviewed. Predictive equations for the mechanical properties of PFRCCs are summarized in this paper. In the end, the characteristics of the interface transition zones between PFs and CCs are analyzed. According to the results of previous studies, the addition of PFs can enhance the flexural strength and tensile strength of CCs, but it can have an uncertain effect on compressive strength. The elastic modulus and fracture behavior of PFRCCs increases with the addition of PFs. At the same time, modification methods have been proved to be useful in reducing the degradation of PFs in CCs. Generally speaking, PFRCCs are new building materials which have extensive application prospects. The aim of this review is to help researchers understand the mechanical properties of PFRCCs and to promote the application of PFRCCs in future projects.
由于植物纤维（PFs）具有优异的力学性能、韧性和可持续性，它们在水泥基凝胶复合材料（CCs）中的应用越来越广泛。研究人员对植物纤维增强水泥基凝胶复合材料（PFRCCs）进行了大量研究。基于这些研究，本综述总结了植物纤维的化学成分和力学特性。此外，还讨论了基体和植物纤维的改性方法。综述了PFRCCs的力学性能，包括静态和动态性能。本文总结了PFRCCs力学性能的预测方程。最后，分析了植物纤维与水泥基复合材料之间界面过渡区的特性。根据以往的研究结果，添加植物纤维可以提高水泥基复合材料的抗弯强度和抗拉强度，但对抗压强度的影响可能不确定。随着植物纤维的添加，PFRCCs的弹性模量和断裂行为会增加。同时，已证明改性方法有助于减少植物纤维在水泥基复合材料中的降解。一般来说，PFRCCs是具有广泛应用前景的新型建筑材料。本综述的目的是帮助研究人员了解PFRCCs的力学性能，并促进PFRCCs在未来项目中的应用。
