剑麻纤维对再生骨料混凝土性能的影响

The Impact of Kenaf Fiber on the Performance of Recycled Aggregate Concrete

使用建筑废弃材料制作再生骨料配置混凝土可以有效减少天然砂石资源的消耗,同时可以有效减轻建筑垃圾造成的污染。在混凝土中掺入适量剑麻纤维则可以有效提高混凝土力学性能包括韧性和抗断裂能力、抗压强度、抗拉强度、抗弯性能、弹性模量等方面。文章结合国内外研究成果,就骨料混凝土的力学性能、剑麻纤维对再生骨料混凝土力学性能的影响进行分析和综述,并对未来研究进行展望,为剑麻纤维-再生骨料混凝土的实际工程应用提供参考价值。

The utilization of construction waste materials for producing recycled aggregates,along with the co-configuration of aggregate concrete using these recycled aggregates,presents a promising approach to reduce the consumption of natural sand,gravel,and concrete materials.Moreover,it effectively addresses the pollution caused by construction waste.The addition of an appropriate amount of sisal fiber to concrete has shown to significantly enhance its mechanical properties.Drawing upon domestic and international research findings,this paper provides an analysis and review of the mechanical properties of aggregate concrete and the impact of sisal fiber on the mechanical properties of recycled aggregate concrete.Furthermore,it offers insights for future research directions,aiming to provide valuable references for the practical engineering application of sisal fiber-reinforced recycled aggregate concrete.
