Types of fly ash . Fly ash is produce in large quantities at coal / lignite thermal power stations. Application of technologies for collection, transportation and deposition of ash results in its availability primarily in four forms, namely; dry fly ash/ hopper ash, bottom ash, pond ash and mound ash, which are described below:
Fly ash quality measures have been established based on major element chemistry and mineralogy . 10 The cementing efficiency of fly ash in concrete has been shown to be related to the physical and chemical properties of the fly ash.
The samples b and e have 5% fly ash; they contain different types of fly ash, and l includes two samples with 10% fly ash, with different types of fly ashes (C and OE). No samples were chosen from the second group because their compressive strength results were similar to those of the first group. The selected samples have the best mechanical strengths in their respective groups.
Generally, fly ash are divided by two types which are fly ash Class C and fly ash Class F. Fly ash from class C usually formed from the combustion of younger lignite or sub- bituminous coal while

Types of fly ash bricks. Flyash bricks can be divided into the following types . Clay Flyash Bricks. Manufacturing process of clay flyash bricks by manual or extrusion process involves mixing of flyash (60 %) with clay of moderate plasticity. The green bricks are dried under ambient atmospheric conditions or in shed to equilibrium moisture level of below 3 percent. Dried bricks are fired in
Thus a fly ash classification system could be developed based on a set of standard fly ash glass compositions that would predict the reactivity of the fly ash and hence its performance as a supplementary cementitious material.
Despite the reference in ASTM C 618 to the classes of coal from which Class F and Class C fly ashes are derived, there was no requirement that a given class of fly ash must come from a specific type of coal. For example, Class F ash can be produced from coals that are not bituminous. and bituminous coals can produce ash that is not Class F (Halstead,1986). It should be noted that current
Fly ash clay bricks are manufactured with clay and fly ash—a byproduct of coal burning—fired at about 1,000 degrees C. Because fly ash contains a high volume of calcium oxide, this type of brick is sometimes described as self-cementing, since it expands when exposed to moisture.

The leaching behavior of arsenic (As) in coal fly ash collected from two different types of coal fired power plants (unit 1 and unit 2: 600 MWe) has been investigated to understand their behavior during combustion and effect of different boiler types on arsenic leachability.
Despite the reference in ASTM C 618 to the classes of coal from which Class F and Class C fly ashes are derived, there was no requirement that a given class of fly ash must come from a specific type of coal. For example, Class F ash can be produced from coals that are not bituminous. and bituminous coals can produce ash that is not Class F (Halstead,1986). It should be noted that current
