摘　　要：利用正交试验进行自密实混凝土的配合比设计,并通过自密实混凝土工作性能的测试方法分析及试验研究,分析了粉煤灰、高效减水剂等因素对新拌混凝土的流动性、黏性、抗离析能力的影响,提出了影响自密实混凝土工作性能的相关关系。The orthogonal experimental design of mix proportion for self-compacting concrete was used and some test methods of workability were carried out.The influence of fly ash and high range water reducing admixtures on flowability and stability and viscosity of fresh concrete were analyzed and some factions of affecting workability were proposed based on these investigations.
