粉煤灰影响高性能混凝土工作性能的试验研究

The Experiment Research on Influence of Fly Ash with Workability of High-Performance Concrete

研究了高性能混凝土影响因素的主次关系和粉煤灰对高性能混凝土的影响．认为： 水泥和粉煤灰组成的高性能混凝土中凝胶材料比例的提高对高性能混凝土的和易性具有明 显改善作用，粉煤灰的不同品质和相同品质不同掺量对高性能混凝土的和易性、 ２８天抗压 强度具有不同的影响．本文对粉煤灰影响ＨＰＣ的作用机理也进行了初步探讨．

This essay discusses the relationship between the elements and components which compose High- Performansce Concrete (HPC), especially the impact that Fly Ash has on HPC. The binder of HPC is composed of cement and fly ash, with the relative percentage of each determining the consistency and performance of the HPC. Different fly ash quality and quantity influences the HPC consistency as does R28. This essay also analyses how fly ash influences the action mechanism of HPC.
