摘要
通过研究细骨料中不同石粉掺量在对碾压和常态混凝土工作性能、力学性能和变形性能的影响,确定了石粉的最优掺量,并对其进行了机理分析。试验结果表明:碾压混凝土中石粉最优掺量为16.0%～18.0%,常态混凝土用砂石粉含量不宜超过14.0%,混凝土的综合性能最好。
Throagh the study of workability,mechanical properties and deformation properties between RCC and normal concrete with the different stone powder content in fine aggregate.The optimal stone powder content and the action mechanism of stone powder between RCC and normal concrete were analyzed.The test results showed that the optimal stone powder content in RCC was between 16.0%~18.0% and not more than 14.0% in normal concrete.When stone powder content in sand was the best,the concrete can attain optimal combined properties.
