摘要
通过大量室内试验,并采用相关试验分析方法,研究了不同石粉含量对机制砂混凝土工作性、抗压强度、干缩性能等三大重要性能的影响,总结出了石粉含量对机制砂混凝土工作性、抗压强度、干缩性能的影响的一些规律,为配制中低强度机制砂混凝土时如何选择合理的石粉含量提供一些参考和理论依据。
Though many indoor tests and by adopting related test analysis methods, the influences of different limestone powder content on three important performances of machine - made sand concrete were studied in this paper. The three important performances are workability, compressive strength and dry shrinkage property. Some rules for influences of limestone content on the above three important performances of machine- made concrete were summarized, which could provide some reference and theory basis for how to choose reasonable limestone content when preparing machine- made sand concrete.
