摘　　要：基于再生混凝土的研究进展,从再生骨料界面过渡区特点入手,分析了二次搅拌工艺的作用机理及对再生混凝土强度的影响,并进行了对比试验,表明二次搅拌工艺可以提高再生混凝土强度,从而为再生混凝土的研究提供参考。Based on the advance of recycled aggregate Concrete,by discussing the characteristic of interfacial transition zone of recycled aggregate, the mechanism of secondary mixing process and its effect to compressive strength of recycled aggregate concrete are analyzed.Meanwhile, the comparative tests are experimented.It indicate that the secondary mixing process can improve compressive strength of recycled aggregate concrete.The conclusion may give the reference to the research on recycled aggregate concrete.
