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．
The relationship between primary and secondary factors affecting high performance concrete and fly ash on high performance concrete were studied. It is considered that the improvement of the proportion of gel material in high performance concrete composed of cement and fly ash has a significant improvement on the workability of high performance concrete. The different quality of fly ash and the same quality and different content of high performance concrete Workability, 28 days compressive strength have different effects. In this paper, the mechanism of action of fly ash on HPC is also discussed.
