Sl.No. Synosis Points
1 Ultrafine fly ash is a very fine pozzolanic material (pulverized fuel ash) composed of ultrafine, glassy, spherical particles (of average size 3 to 5 micron) produced through multistage classification of selected fly ash conforming to IS 3812 (Part 1): 2013 ‘Pulverized fuel ash — Part 1 For use as pozzolana in cement, cement mortar and concrete (third revision)’.
2 The fine size of ultrafine fly ash particles and the associated higher reactive surface area, helps achieving higher early strength and lower permeability of the concrete mixes due to mechanical packing effect of well graded fine particles.
3 This standard provides another option to concrete users to the existing ultrafine materials such as silicafume, metakaolin, and ultrafine GGBS.
