Abstract:

Fly Ash is the maximum solid waste pollution source in China,its high-value application can not only turn waste into treasure,but also it is an important technical and economic policy in China's economic construction.It is an important means to solve the contradiction between power production pollution and resource shortage in China.The preparation of fly ash ceramsite has great significance for the resource utilization of fly ash.The preparation methods and research progress of fly ash ceramsite at home and abroad were reviewed,and the technology and mechanism of preparation of fly ash ceramsite by calcination and non-calcination methods were analyzed in detail.The market application fields and adopted standards of fly ash ceramsite were introduced,the problems and solutions in the process of comprehensive utilization were put forward,and the development trend in the future was prospected.

Key words: fly ash, sintered ceramsite, non-fired ceramsite
