jaue2021-081: A study on the properties of modified fly ash produced from three kinds of coal by flotation method

Abstract

So far, there are still various problems in expanding the use of fly ash for concrete. Due to the different treatment
methods used in coal production areas and power plants, the physical properties and quality of fly ash are also very
different, and the impact of fly ash on concrete also depends on these factors. Therefore, when expanding the use
of fly ash for concrete, it is necessary to understand the influence of fly ash on concrete in various countries and
regions, and to stabilize the quality of fly ash by controlling the quality of fly ash. Therefore, this paper mainly
studies the various properties of fly ash in different countries.
