[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged by coal-fired power plants. With the development of the power industry, the fly ash emissions from coal-fired power plants have increased year by year, becoming one of the largest industrial waste residues in my country. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. However, fly ash can be used as a resource, such as as an admixture for concrete.

[0003] The existing fly ash admixture is generally added directly to the cement raw materials, which results in the inability to add fly ash quantitatively, resulting in different local proportions when the cement raw materials and fly ash are mixed, resulting in deviations in the quality of the produced cement.
