Fly ash is the solid waste after the combustion of pulverized coal in coal-fired power plants.Its increasing accumu-lation not only occupies a large amount of land resources,but also destroys the original natural environment and causes seri-ous pollution.In recent years,the treatment and resource utilization of fly ash has received widespread attention. Improving the comprehensive utilization of fly ash is the key to stimulate the potential activity of fly ash.The physical activity and chemi-cal activity sources of fly ash were introduced,and the physical activation,hydrothermal activation and chemical activation technology and activation mechanism of fly ash activity were reviewed,which provided reference for the subsequent activation research and large-scale utilization of fly ash.The fly ash could be activated by using various methods,however,when selected the sole activation method,it needed high investment and suffered low activation degree.In the future,fly ash excitation tech-nology would develop in the direction of multiple means.
