摘　　要：全面研究了邯郸地区用砖混结构建筑垃圾生成的再生骨料的粒径、堆积密度、吸水率、筒压强度等基本性能。通过试验,分别测试了以建筑垃圾为骨料的再生混凝土的干表观密度、抗压强度、抗渗性、抗冻性等相关的物理力学性能、以混凝土废渣为粗骨料的再生混凝土的抗压强度和以建筑垃圾作为细骨料等体积替代砂浆中的砂的再生砂浆的抗压强度,并分别与普通混凝土和砂浆对比分析。试验结果表明:以建筑垃圾为骨料的再生混凝土具有良好的基本力学性能,强度最高可达C30;用混凝土废渣作为粗骨料配制的再生混凝土的强度等级可达C50;再生砂浆的强度不降低。The basic properties of recycled aggregates such as partical size, bulk density, water ab- sorption, cylinder compressive strength were studied roundly and recycled aggregates were made from construction waste of brick structure. By experimenting, related to the physico -mechanical proper- ties of recycled concrete made from construction waste such as dry apparent density, compressive strength, impermeability, frost resistance were tested; The compressive strength of recycled concrete whose recycled coarse aggregates were made from concrete waste residue was measured and made a comparison with that of ordinary concrete ; Through such as volume to replace sand in mortar the com- pressive strength of recycled mortar whose fine aggregates were made from construction waste was stud- ied and made a comparison with that of ordinary mortar. The experimental results showed that recycled concrete made from construction waste has a good basic mechanics performance and its compressive strength was up to C30;The compressive strength of recycled concrete whose recycled coarse aggre- gates were made from concrete waste residue was up to C50; The compressive strength of recycled mortar didnt come off. The research results can be used for reference in the engineering application and scientific research. , and for the further study of recycled concrete and mortar have provided the certain theory basis.
