Abstract:
Fly ash mainly comes from thermal power generation, metal smelting, heating and other coal consumption links. if can not be effectively used will bring harm to human life and production. In China. The fly ash yield is huge, and the regional distribution is uneven and seasonal, which leads to the low utilization rate of fly ash and large regional differences. This paper summarizes the research progress of comprehensive utilization of fly ash in the fields of building materials, environmental protection, agriculture, chemical industry and metallurgy, analyzes the application prospect of fly ash, and provides a train of thought for the subsequent utilization research of fly ash.
