| Abstract: | 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. |
| Keywords: | fly ash concrete strength |
