The carbonaceous material in fly ash is composed of angular particles. The particle size distribution of most bituminous coal fly ashes is generally similar to that of a silt (less than a 0.075 mm or No. 200 sieve). Although sub bituminous coal fly ashes are also siltsized, they are generally slightly coarser than bituminous coal fly ashes.
