CHARACTERIZATION OF FLY ASH FOR THEIR EFFECTIVE .

9 2.2 CLASSIFICATION. Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 100 µm.

Fly Ash Classification Old and New Ideas

Fly ash classification based on weight percent CaO is a far better approach than the traditional ASTM C 618 standard. The Canadian Standards Association (CSA) specification of low -, intermediate-, and high- CaO fly ashes may be a better approach to fly ash classification than the more simplified concept of splitting fly ashes into Class F and Class C at 18% CaO.

Classification: Fly Ash Concrete | ConcreteBasics ...

Classification of Fly Ash. Two major classes of fly ash are specified in ASTM C 618 on the basis of their chemical composition resulting from the type of coal burned; these are designated Class F and Class C.. Class F is fly ash normally produced from burning anthracite or bituminous coal, and Class C is normally produced from the burning of sub-bituminous coal and lignite.

CHAPTER 4 PROPERTIES OF MATERIALS 4.1 Fly Ash

4.1.2 Classification of Fly Ash According to IS 3812-1981, there are two grades of Fly Ash I, Grade I fly ash, which are derived from bituminous coal having fractions SiO 2 +Al 2 O 3 +Fe 2 O 3 greater than 70 %. II, Grade II Fly ash, which are derived from lignite coal having fractions SiO 2 +Al 2 O 3 +Fe 2 O 3 greater than 50 %.

Fly Ash - A Hazardous Material? - Precast concrete

Aug 23, 2010 · ASTM C 618 classifies fly ash based on the sum of its primary constituents (SiO2, Al2O3, Fe2O3): when this sum exceeds 50%, it is classified as a Class C fly ash; when the sum equals or exceeds 70%, the Class F designation is used. Precast producers like fly ash because it reduces material cost and results in stronger concrete.
