摘要/Abstract

摘要： 再生骨料及其制品是促进建材行业健康发展的有效方式。但再生骨料具有表观密度小及孔隙率等缺点,难以应用于工程结构承重构件。纤维改性再生混凝土材料性能作为一项工程技术,可大幅提升再生混凝土的力学性能,降低了建筑业对天然砂石资源的需求,有效节省了天然砂石资源。本文主要介绍了纤维再生混凝土材料性能,探讨了其耐高温性能,总结了其耐久性能相关试验成果,分析了纤维改性再生混凝土性能的机理,并提出了其现阶段研究存在的问题,进一步展望了其未来的发展方向。

Abstract: Recycled aggregates and their products are an effective way to promote the healthy development of the building materials industry. However, recycled aggregates are difficult to apply to structural member of engineering structure, due to their low apparent density and high porosity. As an engineering technology, the performance of fiber-modified recycled concrete materials can greatly improve the mechanical properties of recycled aggregate concrete (RAC), reducing the demand for natural sand and gravel resources in the construction industry, and effectively saving natural sandstone resources. The performance of fiber recycled concrete materials was mainly introduced, and its high temperature resistance was discussed. The durability test results were summarized. The mechanism of fiber modified recycled concrete performance was analyzed. The existing problems in the research were also proposed. Its future development direction is further prospected.

Key words: fiber recycled aggregate concrete, mechanical performance, high temperature behavior, durability
