The discharge and accumulation of a large amount of fly ash can pose a significant threat to the environment,and its resource utilization is beneficial for environmental protection.The development of fly ash recycling technology from the perspectives of chemical composition,physical properties,fillers and high added value utilization were analyzed in this article.The reasons for the accumulation of fly ash,the relationship between resource recycling technology and transportation radius,and the contradiction between resource recycling technology and processing capacity were discussed,and it put forward corresponding countermeasures against these existing problems:addressing the sustainability of fly ash generation for bulk consumer goods,high added value to cope with the limitation of transportation radius,and the diversification of high value-added products in response to the lack of processing capacity.
