Concrete crack is one of the main problems observed in concrete technology due to drying shrinkage. Incorporating fibers in concrete production is one of the mechanisms implemented to mitigate cracks. Nowadays, investigators concentrate on different techniques to replace human-made fiber with existing natural fibers for fiber-reinforced composite material. Utilization of natural fiber has an initiation for the development of eco-friendly materials by reducing damages caused by human-made materials and saving nonrenewable resources. Natural fibers are readily and abundantly available, sustainable, and biodegradable, with low cost and low density, and have superior specific properties. Nevertheless, there are some limitations of natural fiber compared to human-made fiber. Consequently, significant energy was applied to alter natural fiber’s surface and morphology using physical, chemical, and biological treatment techniques to overcome the limitation. The primary intention of surface treatment is to modify the bond between the fiber surface and the polymer matrix. However, based on this literature review, there were no specific treatment techniques to be followed to select the best one from the others as criteria. It should include all parameters to consider starting from the stage from the cradle to the grave, cost of chemicals, transportation, and labors, including energy consumption and effluent energy. Additionally, their environmental effect also investigated in detail to compare each other.

用于混凝土路面的天然纤维处理

由于干缩,混凝土裂缝是在混凝土技术中观察到的主要问题之一。将纤维掺入混凝土生产中是减轻裂纹的机制之一。如今,研究人员专注于用不同的技术将人造纤维替换为纤维增强复合材料的现有天然纤维。通过减少人造材料造成的损害并节省不可再生资源,天然纤维的利用为开发环保材料提供了开端。天然纤维容易获得且可大量获得,可持续且可生物降解,成本低且密度低,并且具有优异的特定性能。然而,与人造纤维相比,天然纤维仍有一些局限性。所以,为了克服这种局限性,大量的能量被用于通过物理,化学和生物处理技术来改变天然纤维的表面和形态。表面处理的主要目的是改变纤维表面与聚合物基体之间的结合力。但是,根据该文献综述,没有要遵循的特定治疗技术来选择其他最佳治疗方法作为标准。它应该包括从摇篮到坟墓的阶段要考虑的所有参数,化学品,运输和人工的成本,包括能源消耗和废水能。此外,还对它们的环境影响进行了详细研究以相互比较。表面处理的主要目的是改变纤维表面与聚合物基体之间的结合力。但是,根据该文献综述,没有要遵循的特定治疗技术来选择其他最佳治疗方法作为标准。它应该包括从摇篮到坟墓的阶段要考虑的所有参数,化学品,运输和人工的成本,包括能源消耗和废水能。此外,还对它们的环境影响进行了详细研究以相互比较。表面处理的主要目的是改变纤维表面与聚合物基体之间的结合力。但是,根据该文献综述,没有要遵循的特定治疗技术来选择其他最佳治疗方法作为标准。它应该包括从摇篮到坟墓的阶段要考虑的所有参数,化学品,运输和人工的成本,包括能源消耗和废水能。此外,还对它们的环境影响进行了详细研究以相互比较。它应该包括从摇篮到坟墓的阶段要考虑的所有参数,化学品,运输和人工的成本,包括能源消耗和废水能。此外,还对它们的环境影响进行了详细研究以相互比较。它应该包括从摇篮到坟墓的阶段要考虑的所有参数,化学品,运输和人工的成本,包括能源消耗和废水能。此外,还对它们的环境影响进行了详细研究以相互比较。
