Fly ash is commonly used in concrete in replacements ranging from 0 to 30 percent by mass of the total cementitious material. However, research has shown that using a 50
For fly ash use in concrete applications, fineness is defined as the percent by weight of the material retained on the mm (No. 325) sieve. A coarser gradation can result in a less reactive ash and could contain higher carbon contents.
Fly ash also improves the permeability of concrete by lowering the watertocement ratio, which reduces the volume of capillary pores remaining in the mass. The spherical shape of fly ash improves the consolidation of concrete, which also reduces permeability.
CLASS F FLY ASH. Composition. Class F fly ash is designated in ASTM C 618 and originates from anthracite and bituminous coals. It consists mainly of alumina and silica and has a higher LOI than Class C fly ash.

Since a huge quantity of cement is used in concrete in mass concrete construction and the cost of fly ash is negligible as compared to that of the cement, the use of fly ash concrete brings about a substantial saving in cement consumption and overall construction cost.
Fly ash admixtures can lengthen the time it takes for concrete to set. Sometimes this is desirable, particularly in hot weather which speeds up concrete set times, but at other times it is an inconvenience and can cause delays in construction.
Fly Ash for Concrete Pavement C urrent Wisconsin Department of Transportation (WisDOT) specifications only permit Class C fly ash for use in Portland cement concrete in pavements. Class F fly ash sources were eliminated from WisDOT specifications in the 1990s due to high values of loss on
Fly ash is considered the modernday "Pozzolan," a word that comes from the Italian city, Pozzuoli, which most consider the birthplace of ash concrete technology. Pozzolan is a siliceous material that by itself possesses no cementitious value.
Fly ash by mixing efficiently with the concrete mix can replace Portland cement that in turn can aid in making big savings in concrete material prices. It is an environmentallyfriendly solution. It improves the strength over time and offering greater strength to the building.
