of the biggest advantages of fly ash is its fineness, which usually allows it to be fed directly to the separator feed. The major part of the fly ash particles will be carried directly to the finished product, leading to a higher overall production rate of existing grinding installations. Limitations The general limitations of fly ash usage

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.

Fly ash has a high potential to be converted into geopolymeric material due to its abundant supplies and low cost. However, large particle size of the fly ash caused low reactivity which results in low properties of the end product. The improvement on the fly ash properties by mechanical activation allows it as a new possible raw material in wider application besides solving the low reactivity ...
