摘　　要：本文利用碱激发效应,在拌制再生混凝土过程中加入矿渣来调整其水化程度,采用部分取代天然骨料的方式,用建筑废弃物(碎石)作为混凝土的骨料,通过调整骨料配比来制备力学性能优良的再生骨料混凝土。并检测其力学性能和对其微观界面进行分析,得出不同取代率时,再生混凝土的力学性能变化规律。In this paper,alkali stimulation effect is used to add slag to adjust the degree of hydration during the process of mixing recycled aggregate concrete.Partially substituting natural aggregates, the construction waste （crushed stone） is used as the aggregate of concrete,by adjusting the ratio of aggregate to prepare excellent me-chanical properties of recycled aggregate concrete.The mechanical properties of the recycled concrete were tested and the microscopic interface was analyzed.The changing regularity of the mechanical properties of the recycled concrete with different substitution rates was obtained.
