What Is Fly Ash Properties - ultrafinegrinder

2021-9-30  The standard of fly ash is also divided into national standard grades: Grade I fly ash is 2.6g/cm3. The particle shape of fly ash determines the density of fly ash to a certain extent, and it is related to the iron composition contained in fly ash. The density of fly ash is 1.07 ~ 2.4 g / cm3. Bulk density: generally 555 ~ 700 kg / m3.
