不同机制砂对混凝土工作性能的影响及改善措施研究

Research on the Influence of Different Mechanism Sands on the Working Performance of Concrete and Improvement Measures

文中在明确不同机制砂对混凝土工作性能的影响基础上,阐述机制砂级配、岩性和颗粒形状对混凝土工作性能的主要影响因素,结合实际案例,调整混凝土配合比与外加剂配方,改善混凝土工作性能,取得了良好的试验效果。

On the basis of clarifying the influence of different types of machine made sand on the workability of concrete,this article elaborates on the main influencing factors of machine made sand gradation,lithology,and particle shape on the workability of concrete.Combining with practical cases,it explores the influence of machine made sand on the workability of concrete,adjusts the concrete mix ratio and admixture formula,improves the workability of concrete,and achieves good experimental results.
