Ppt On Fly Ash Utilization. Minimum of fly ash by weight related Indian Standards 1 Fly ash bricks blocks tiles etc. Introduction Fly ash is a fine grey powder consisting mostly of spherical glassy particles that are produced as a by-product in coal fired. As nearly 73 of the countrys total installed power generation capacity is thermal of which coal-based generation is 90. Coal based thermal power plants generate huge amount of fly ash that is a major problem of disposal of fly ash in India.
Indiacommissioned during 1994 as a joint activity of Department of Science Technology DST Ministry of Power MOP and Ministry of Environment Forests MOEF with Department of Science Technology as the nodal agency after its approved period ie. ConclusionIf Fly Ash bricks can replace 50 of clay bricks then itwill reduce emission of green house gas by 435000 tonseach yearFly Ash based Bricks industries needs fragmented marketthat are serviced by plants located in the local area. Though there has been a steady progress in fly ash utilization from 1990 there is a long way to go to reach the target of 100 per cent fly ash utilization. Of the hundreds of millions of metric tons of fly ash that are produced annually on a worldwide basis only a small portion eg 20 to 40 of the fly ash is re-used for productive purposes such as an additive or stabilizer in cement.

Advantage of fly ash bricks over red bricks were explained in the workshop and methodology of making fly ash. With fly ash lime gypsum stone dust etc. Thepresent utilization of Fly Ash in the country is nominal ascompared to other advanced countries. Owing to its pozzolanic properties fly ash is used as a replacement for some of the Portland cement content of concrete Use of fly ash as a partial replacement for Portland cement is generally limited to Class F fly ashesFly ash can substitute up to.
