Penggunaan Fly Ash. Fly ash lebih disukai untuk berbagai aplikasi dan digunakan dalam: Pembuatan Semen Portland Pozzolana. Sesuai 'IS 1489 (Bagian 1): 1991' (Spesifikasi Semen Portland-Pozzolana), bahan fly ash harus 10-25% menurut berat Semen Portland Pozzolana.
THE USE OF FLY ASH IN BUILDING MATERIALS diverts millions of tons of ash from the landfills each year, increases the constructability and durability of concrete and brick, partially replaces energy-intensive Portland cement, and is recognized by the U.S. Green Building Council's LEED rating system as a post-industrial recycled material.
Fly ash is produced from the burning of pulverized coal in a coal-fired boiler. It is a fine-grained, powdery particulate material that is carried off in the flue gas and normally collected from the flue gas by means of electrostatic precipitators, baghouses, or mechanical collection devices such as cyclones.
