摘要
研究了机械活化粉煤灰、化学活化粉煤灰和复合活化粉煤灰对大掺量粉煤灰混凝土的增强作用 ,结果表明粉煤灰的复合活化可显著提高大掺量粉煤灰混凝土的早期及 2 8d强度。
In this paper, effects of mechanical, chemical and composite methods on the activity of fly ash were studied, and the activation mechanisms of above methods were analysed. Results showed that composite activation of fly ash could improve early and 28-day strength of high-volume fly ash concrete.
