Feb 21, 2020 · Fly Ash: Fly ash is a by product of coal fired electricity generating power plants. Mainly composed of combustible elements such as carbon, hydrogen and oxygen (nitrogen and sulfur being minor elements), and non-combustible impurities (10 to 40%) usually present in the form of clay, shale, quartz, feldspar and limestone.
Fly ash - Wikipedia
The effect of fly ash on the environment can vary based on the thermal power plant where it is produced, as well as the proportion of fly ash to bottom ash in the waste product. This is due to the different chemical make-up of the coal based on the geology of the area the coal is found and the burning process of the coal in the power plant.

Uses, Benefits, and Drawbacks of Fly Ash in Construction
Feb 17, 2019 · Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.
Jan 07, 2016 · However, admixture used in RMC is modified to meet the requirement of pumpable concrete and other properties of concrete. The types of admixture used in RMC are generally termed as Super plasticizers. 12. FLY ASH Fly ash is a by-product from coal-fired electricity generating power plants.
Fly Ash - Properties, Types, Mechanism and Uses
The specific gravity of fly ash ranges from a low value of 1.90 for a sub-bituminous ash to a high value of 2.96 for an iron-rich bituminous ash. 3. Size and Shape of Fly Ash. As the flyash is a very fine material, the particle size ranges in between 10 to 100 micron. The shape of the fly ash is usually spherical glassy shaped.
