Fly ash is converted into coarse aggregates by 'pelletising' followed by 'sintering' actions. Powdery granules of FA can be agglomerated minerologically by sintering and then used as CA. These sintered fly ash aggregates (SFAAs) are highly porous and hence, concretes made from them aggregates would be also lightweight in nature.Corpus ID: 53685491.
