    May 22, 2010 Ultrafine fly ash is a processed ash generated from a Class F fly ash source. The parent ash is passed through a classifier where the coarse particles are removed and the fines are collected and stored separately. While the average particle size of raw or unprocessed ash is around 20 to 30 microns and the largest at 100 microns, an ultrafine

    Aug 11, 2021 Fly ash (FA) showed low reactivity when being used to prepare the binder for cemented paste backfill (CPB). In the present work, wet-grinding treatment was used to increase the pozzolanic reactivity of FA and promote its sustainable utilization. The results showed that wet-grinding could be a suitable and efficient technology for FA pretreatment. Wet-grinding strongly modified the structure of
