| 摘 要： | 该文介绍了,在福永高速工程中率先推广和使用机制砂混凝土的情况。在实践中,研究了不同灰水比条件下机制砂混凝土抗压强度与灰水比的关系。试验结果表明:机制砂混凝土的强度并不完全符合JTG 55-2000《普通混凝土配合比设计规范》中配制强度fcu,o与灰水比(C/W)的关系。其线性回归系数发生了一定变化,与灰水比的关系可用线性关系式表示为:fcu,o=0.84fce(C/W-0.82)。

| Abstract: | The article introduces the situation of the machine-made sand concrete firstly popularized and used in Fuyong Expressway Project,and analyzes the relationship of compressive strength and cement water ratio of the machine-made sand concrete under the different cement water ratios in the practices.The experimental result makes clear that the strength of machine-made sand concrete does not completely satisfy the relation of the prepared strength fcu,o and cement water ratio(C/W) in JTG55-2000 Ordinary Concrete... |
