摘　　要：试验研究了颗粒整形再生骨料混凝土、简单破碎再生骨料混凝土和天然骨料混凝土的力学性能.结果表明:全组分颗粒整形再生骨料混凝土的力学性能低于天然骨料混凝土,但大大优于简单破碎再生骨料混凝土.另外,颗粒整形再生粗骨料配置的混凝土力学性能明显高于简单破碎再生骨料混凝土与全组分颗粒整形再生混凝土,略低于天然骨料混凝土,该试验结果对于工程实践具有一定指导作用.Mechanical properties of particle shaped recycled aggregate concrete, simplycrushed recycled aggregate concrete and natural aggregate concrete are studied in this paper. The experimental results show that mechanical properties of 100% particle shaped recycled aggregate concrete are lower than these of natural aggregate concrete. However, they are significantly higher than these of simply-crushed cycled aggregate concrete. Furthermore, mechanical properties of particle shaped recycled coarse aggregate concrete are notably higher than these of simply-crushed cycled aggregate concrete and 100% particle shaped recycled aggregate concrete. And they are slightly lower than these of natural aggregate concrete. Finally, the experimental results also provides reference for engineering practices.
