该文研究了低品质粉煤灰的活性指数和其对胶砂流动度和混凝土各项性能的影响。结果表明:低品质粉煤灰的活性指数随着其细度的增加而增加,但增加趋势逐渐放缓;掺入低品质粉煤灰的胶砂流动度随着细度的增加呈现先增大后减少的趋势;低品质粉煤灰能够满足混凝土的各项性能,所以能够在工程应用中大量使用。

This paper studies the activity index of flash of low quality with its impact on fluidity of mortar and on the properties of concrete. The results show that the activity index of low quality fly ash increases with the increase of its fitness, but the increase trend is steadily slowed down, and that the fluidity of mortar mixed with low quality fly ash firstly increases and then decreases with the increase of fitness, so it can be widely used in the engineer-ing application for its capability of meeting the various properties of concrete.
