Synopsis

Fly ash is typically finer than Portland cement and lime. Fly ash consists of silt-sized particles which are generally spherical; typically ranging in size between 10 and 100 micron These small glass spheres improve the fluidity and workability of fresh concrete. Fineness is one of the important properties contributing to the pozzolanic reactivity of fly ash. Under a microscope, they look like tiny bubbles of various sizes. The annual generation of fly ash has increased from about 1 million tonnes in 1947 to about 40 million tonnes during 1994 and to about 112 million tonnes at present. As per an estimate of FAUP, TIFAC, the annual ash generation figures are expected to reach about 170 million tonnes by 2012 and 225 million tonnes by 2017.
