摘要/Abstract

摘要： 废弃口罩的回收利用是应对环境污染和资源浪费的关键之一。作为口罩的主要成分,聚丙烯纤维的可再生性使其在水泥基建筑材料中的应用逐渐受到关注。本文综述了废弃口罩在水泥基建筑材料中的应用现状,总结了废弃口罩的回收技术,包括裁剪、热挤压、碎纸机和破壁机粉碎等。研究表明,掺入废弃口罩纤维对混凝土、砂浆和道路基层等材料的力学性能、流动性和耐久性产生了显著影响。此外,废弃口罩纤维的尺寸和处理方式对水泥基建筑材料的力学性能也有重要影响。同时,不同的应用场景对材料性能的影响也存在差异。上述研究结论可为水泥基建筑材料的可持续发展提供理论支持和实践指导。

Abstract: The recycling of discarded masks has become a key research direction to deal with environmental pollution and waste of resources. As the main component of masks, polypropylene fiber has attracted more and more attention in the application of cement-based building materials due to its renewability. This paper reviews the application status of discarded masks in cement-based building materials, and summarizes the recycling technologies of discarded masks, including cutting, hot extrusion, shredder and wall breaker. Studies have shown that the incorporation of discarded mask fibers has a significant impact on the mechanical properties, fluidity and durability of materials such as concrete, mortar and road base. In addition, the influences of different application scenarios on the performance of materials are also different, which provides a basis for further exploring the resource utilization of discarded masks and provides a theoretical basis and practical guidance for the sustainable development of cement-based building materials.

Key words: discarded mask, polypropylene fiber, cement, building material, resource reuse
