Abstract

Plastic waste management is of global concern while construction industry keeps searching for innovations to become more sustainable. In this scenario, recycling plastic waste as fibers for reinforcement of concrete stands out as a promising alternative to address both problems. In the last decade, many reviews have focused on how plastic fibers affect concrete properties and how waste can be used to produce these fibers. This paper presents an umbrella review of 47 previous reviews published from 2008 to 2021, covering papers from 1949 to 2021. As a result, bases were set to clarify the full life cycle of recycled plastic fiber-reinforced concrete (RP-FRC), including circularity strategies, to strengthen consistent contributions to the area in the future. The review compares and discusses the types of plastic waste suitable for producing plastic fibers, the effects of recycled plastic fibers on concrete properties and the sustainability of this recycling alternative. Finally, recommendations and unanswered questions for further research were formulated.

再生塑料废物作为混凝土纤维的可持续性:综述

塑料废物管理是全球关注的问题，而建筑业也在不断寻求创新，以提高其可持续性。在这种情况下，回收塑料废物作为钢筋混凝土的纤维作为解决这两个问题的有希望的替代方案脱颖而出。在过去的十年中，许多评论都集中在塑料纤维如何影响混凝土性能以及如何利用废物来生产这些纤维上。本文对2008年至2021年发表的47篇综述进行了综述，涵盖了1949年至2021年的论文。因此，基地的设置是为了阐明再生塑料纤维增强混凝土(RP-FRC)的整个生命周期，包括循环策略，以加强未来对该地区的一致贡献。本文比较和讨论了适合生产塑料纤维的塑料废物的种类、再生塑料纤维对混凝土性能的影响以及这种再生替代品的可持续性。最后，提出了建议和有待进一步研究的问题。图形抽象

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
