摘　　要：对普通混凝土、石屑特细砂混凝土和再生骨料混凝土分别进行了基本性能试验研究,包括塑性混凝土性能、硬化混凝土力学性能和耐久性。试验结果表明,石屑特细砂混凝土和再生骨料混凝土具有较好的力学性能和耐久性,但碎屑特细砂混凝土的收缩值相对较大。The basic properties of the ordinary concrete, the stone chip and extra fine sand concrete, the recycted ag- gregate concrete are-studied, including the plastic properties of concrete, the mechanical properties and durability of hard- ened concrete. The results show that the stone chip and extra fine sand concrete, the recycled aggregate concrete have high strength and good durability, and dry shrinkage of the stone chip and extra fine sand concrete is bigger.
