| 摘 要： | 对再生骨料混凝土27组立方体试件和5组棱柱体试件进行了试验,主要研究了再生骨料混凝土的水灰比与立方体抗压强度的关系,以及立方体抗压强度与棱柱体抗压强度和弹性模量之间的换算关系。结果表明:相对于普通混凝土,再生骨料混凝土立方体抗压强度和弹性模量有所降低,但棱柱体抗压强度略为升高。

| Abstract: | Based on the test of 27 group cubes and 5 group prisms,the relationship between cubic compressive strength and water-to-cement ratio,the relationship between cube compressive strength and prism strength,and the relationship between cubic compressive strength and Young's modules of recycled concrete are investigated. The results show that the cubic compressive strength and Young's modulus of recycled aggregates concrete are lower than that of natural aggregate concrete.Whereas,the prism compressive strength ... |
