Abstract

Wind power technology can significantly mitigate climate change and alleviate energy supply constraints, and accelerating the development of the wind power industry has become a global consensus. Nevertheless, the impending surge in decommissioned wind turbine blades necessitates urgently exploring efficient valorization pathways. This investigation employs a mechanical recycling method to process decommissioned wind turbine blades into recycled fibers for mortar reinforcement, aiming to develop a cementitious composite material that is competitive in performance and economic impact. The influence of different replacement ratios (0 vol%, 1 vol%, 2 vol% and 3 vol%) of recycled wind turbine blade fibers (RWTBF) on the workability, physical properties, mechanical properties, thermal properties and microstructure of the mortar was systematically investigated. The results indicate that mortar with 2 % RWTBF exhibited a 6.90 % decrease in water absorption, a 20.23 % increase in flexural strength, and a 40.48 % reduction in thermal diffusivity compared with mortar without RWTBF, while demonstrating excellent cost-effectiveness and sustainability. These findings validate the technical feasibility and environmental superiority of RWTBF-reinforced mortar as a sustainable construction material, establishing a synergistic green development pathway for the renewable energy and building sectors.

再生风力涡轮机叶片纤维在砂浆中的增强：综合性能评价

风电技术可以显著减缓气候变化，缓解能源供应紧张，加快发展风电产业已成为全球共识。然而，即将退役的风力涡轮机叶片数量激增，迫切需要探索有效的增值途径。本研究采用机械回收方法，将退役的风力涡轮机叶片加工成再生纤维，用于砂浆加固，旨在开发一种具有性能和经济效益竞争力的胶凝复合材料。系统研究了再生风力发电机叶片纤维（RWTBF）的不同替换率（0 vol%、1 vol%、2 vol%和3 vol%）对砂浆的和易性、物理性能、力学性能、热性能和微观结构的影响。结果表明，与不掺水tbf的砂浆相比，掺2%水tbf的砂浆吸水率降低6.90%，抗折强度提高20.23%，热扩散系数降低40.48%，同时具有优异的成本效益和可持续性。这些研究结果验证了rwtbf增强砂浆作为可持续建筑材料的技术可行性和环境优势，为可再生能源和建筑行业建立了协同的绿色发展路径。

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
