Increased efficacy of fiber incorporation in self-compacting cementitious mixes (SCM) (mortar and concrete) has resulted in increased demand for virgin fibers. Production of virgin fibers consumes natural resources, which is an environmental concern. Researchers have investigated different waste originated fibers as an alternative to virgin fibers in SCM. Two-fold advantages such as effective utilization of the waste and partial relief to the extraction of natural resources can be achieved by incorporating waste originated fibers in SCM. For enhanced real field applications, comprehensive and comparative knowledge on the utilization of waste originated fibers in SCM is required. Therefore, in the present review, research studies on SCM which investigated the use of waste originated fibers such as rubber fiber, plastic bag fibers, polyethylene terephthalate bottle fibers, steel fibers, glass fibers, and carbon fibers are covered. Availability potential, existing recycling methods, and processing of waste into fibers are discussed. A significant variation is observed in the mixing methodology adopted by various researchers to incorporate waste originated fibers in SCM. An up-to-date review and comparative analysis based on performance parameters (fresh, hardened, and durability properties) of various waste originated fiber incorporated SCM revealed the existing research gaps and future research trends in this area.

纤维掺入自密实水泥质混合物（SCM）（砂浆和混凝土）的功效增强，导致对原始纤维的需求增加。原始纤维的生产消耗自然资源，这是环境问题。研究人员已经研究了源自废料的不同纤维，以替代SCM中的原始纤维。通过将源自废料的纤维纳入SCM，可以获得诸如有效利用废料和部分减轻自然资源开采等双重优势。为了增强现场应用，需要在SCM中利用废纤维来源的综合和比较知识。因此，在本综述中，对SCM的研究进行了研究，调查了废旧纤维的使用，例如橡胶纤维，塑料袋纤维，覆盖了聚对苯二甲酸乙二酯瓶纤维，钢纤维，玻璃纤维和碳纤维。讨论了可用潜力，现有的回收方法以及将废物处理成纤维的方法。在各种研究人员采用的将废旧纤维掺入SCM中的混合方法中，观察到了显着变化。基于掺入SCM的各种废纤维的性能参数（新鲜，硬化和耐用性）的最新审查和比较分析，揭示了该领域的现有研究差距和未来研究趋势。在各种研究人员采用的将废旧纤维掺入SCM中的混合方法中，观察到了显着变化。基于掺入SCM的各种废纤维的性能参数（新鲜，硬化和耐用性）的最新审查和比较分析，揭示了该领域的现有研究差距和未来研究趋势。在各种研究人员采用的将废旧纤维掺入SCM中的混合方法中，观察到了显着变化。基于掺入SCM的各种废纤维的性能参数（新鲜，硬化和耐用性）的最新审查和比较分析，揭示了该领域的现有研究差距和未来研究趋势。
