摘　　要：将再生骨料、粉煤灰及硅灰加入到混凝土中,研究其掺量大小对混凝土和易性及抗压强度的影响,通过对比分析各龄期混凝土试件的抗压强度值,筛选出了最优配合比,为进一步加大工业废弃物及建筑废料再利用提供依据。This experiment adds the recycled aggregate,fly ash and silica fume to concrete,study the influence of the size of its content on the workability and compressive strength of concrete,selects the optimal mix ratio according to the analysis of compressive strength value on the concrete specimens at each age,so it provides a basis to further increase the proportion of industrial waste and construction waste recycling.

关 键 词：再生粗骨料 再生细骨料 硅灰 掺量 抗压强度
