摘要
再生混凝土是一种绿色、可循环建筑材料。当其用于结构构件时,可能会因遭受荷载作用而发生疲劳现象。因此,针对不同再生骨料掺合比(0,50%,100%)的再生钢筋混凝土试件进行疲劳强度试验,通过多尺度(微观和宏观)观察并分析试件,分析受轴心和偏心疲劳荷载作用下不同掺合比的再生钢筋混凝土试件疲劳性能差异。此试验方法和数据结果可为研究、分析其在工程中的运用提供基础依据。
In line with efforts to implement sustainable development,recycled concrete made from recycled concrete aggregates could be an ideal solution to preserve resources and the environment.The fatigue behavior of recycled concrete differs from that of other types of concrete on account of the different properties of recycled concrete aggregates.Therefore,using experimental research,the fatigue behavior and multi-scale analysis of recycled concrete are studied in this paper.The present paper investigates the fatigue behavior of the axial and eccentric compression performance of recycled aggregate-reinforced concrete specimens containing 0%,50%,and 100%recycled aggregates.Then,multi-scale(micro-structural and macro-structural)observations of the specimens are obtained.Analysis of the experiment results reveals the feasibility of applying recycled concrete to practical engineering.
