Abstract

Engineered cementitious composite (ECC) reinforced with polyethylene (PE) fiber has large crack width and high production cost, and these two shortcomings affect its application in practical projects. In this study, basalt fiber (BF) was hybrid with PE fiber to achieve cooperative effect, developing a PE/BF-hybrid fiber ECC (PE/BF-HyECC) with tighter crack width and more economic advantages. The impacts of different fiber content on the pore structure, mechanical, and cost performance of PE/BF-HyECC were investigated. The PE/BF-HyECC with positive cooperative effect of 1.5 vol.% PE and 1.0 vol.% BF had higher strength and tighter crack width compared to PE-ECC with 2.0 vol.% PE. Its cost performance ratio was 1.19 to 1.37 times that of PE-ECC with 2.0 vol.% PE. The better performance and higher cost performance of PE/BF-HyECC is expected to expand its practical application.

杂化聚乙烯-钴纤维对 ECC 中裂纹宽度控制和机械性能的协同效应

用聚乙烯（PE）纤维增强的工程水泥基复合材料（ECC）裂缝宽度大、生产成本高，这两个缺点影响了其在实际工程中的应用。本研究将玄武岩纤维（BF）与聚乙烯纤维（PE）进行混合，以达到协同增效的效果，开发出一种裂缝宽度更窄、更具经济优势的聚乙烯/BF-混合纤维 ECC（PE/BF-HyECC）。研究了不同纤维含量对 PE/BF-HyECC 的孔隙结构、机械性能和成本性能的影响。与含有 2.0 Vol.% PE 的 PE-ECC 相比，含有 1.5 Vol.% PE 和 1.0 Vol.% BF 的 PE/BF-HyECC 具有更高的强度和更紧密的裂缝宽度。其性价比是含 2.0 体积%聚乙烯的 PE-ECC 的 1.19 至 1.37 倍。PE/BF-HyECC 具有更好的性能和更高的性价比，有望扩大其实际应用范围。

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
