Ultrafine fly ash generally exhibits similar chemical properties to conventional fly ash but with some distinctions due to its smaller particle size and increased surface area. Ultrafine fly ash typically contains higher levels of reactive silica (SiO2), alumina (Al2O3), and iron oxide (Fe2O3) compared to coarser fly ash particles. Additionally, ultrafine fly ash may have a higher surface area, which can enhance its pozzolanic reactivity and improve its performance as a supplementary cementitious material in concrete applications. However, the exact chemical composition of ultrafine fly ash can still vary depending on factors such as the source of coal and the combustion process.
