摘   要:介绍了植物纤维的分类、成分和性能,总结了植物纤维混凝土的性能改善方法(纤维自身改性、混凝土基体强化),分析了其作用机理。结果表明:对植物纤维进行合理的物理、化学或生物改性均能有效提升植物纤维与混凝土基体间的黏结性能,进而改善植物纤维混凝土的性能;在植物纤维混凝土中掺入适量掺合料(如偏高岭土、粉煤灰等)能有效提高混凝土的韧性、力学及耐久性能。 Abstract: The classification, composition, and properties of plant fibers were introduced, and the methods for improving the performance of plant fiber reinforced concrete(fiber self modification, concrete matrix strengthening) were summarized, and its mechanism of action was analyzed. The results indicate that reasonable physical, chemical, or biological modifications to plant fibers can effectively enhance the bonding performance between plant fibers and concrete matrix, thereby improving the performance of plant fiber reinforced concrete. Adding an appropriate content of admixtures(such as metakaolin, fly ash, etc.) to plant fiber reinforced concrete can effectively improve its toughness, mechanical properties, and durability.
