摘要

研究了粉煤灰原灰粉磨至比表面积500~700 m2 /kg 指标下对粉煤灰需水量比、活性指数以及对混凝土工作性能

和强度的影响规律。利用扫描电子显微镜、激光粒度仪分别从微观形貌和粒度分布方面探究改性机理。结果表明，

粉煤灰磨细到比表面积550~600 m2 /kg时，兼顾需水量比、活性指数、混凝土工作性能和强度等指标，高性能磨细粉煤

灰性能是最优的。

Abstract：

The effects of pulverized fly ash raw ash on water requirement ratio, activity index, working performance and

strength of concrete were studied when the specific surface area of fly ash was 500~700 m2 /kg. Scanning electron microscope

and laser particle size analyzer were used to investigate the modification mechanism from the aspects of microstructure and

particle size distribution. The results showed that when the specific surface area of fly ash reaches 550~600 m2 /kg, the water

demand ratio, activity index, concrete working performance and strength of concrete all can be balanced, indicating that the

performance of high-performance fly ash grinding is the best under this condition.

Key words：
