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 , bag houses, or mechanical collection devices such as cyclones.
Fly ash is commonly used in production of concrete. It is applied as a supplementary cementing material. Initially the idea was to use fly ash for economical reasons - on one hand to utilize fly ash which is an industrial by product, on the other to reduce the amount of costly cement. However, it appears that application of fly ash in concrete has a lot of benefits, mainly by reduction of unwanted hydration heat.
Cement can be replaced with fly ash in concrete. It reacts (si) with ca (oh)2 and produces more csh gel which contributes to strength. With reduced cement, hydration heat will be reduced and hence there is strength gain.
Fly ash is a finely divided residue made from the combustion of pulverized coal that can be used to increase concrete durability and workability, while reducing permeability.
As fly ash contains aluminous and siliceous components, it may form cement when mixed with water if the calcium content of the fly ash is high enough. Similarly, mixing fly ash with lime and water can create a substance similar to Portland cement.
Fly ash can be separated into two main types, known as:
Class F
Class F fly ash contains particles covered in a type of melted glass allowing it to reduce the risk of concrete expansion and increase resistance to sulfates and alkali-aggregate reactions.
Class C
Class C fly ash contains a higher percentage of calcium oxide, making it more effective in strengthening structural concrete.
Applications & Benefits of Fly Ash:
Fly ash is used in commercial and industrial sectors for improving the durability and workability of concrete mixes.
Fly ash is also used as filler in paints, adhesives, and metal and plastic composites.
It's commonly used as structural fill for road construction and fly ash can be used to make bricks, ceramic tiles, plaster, Portland cement, and ready-mix cement.
Fly Ash a byproduct derived from the combustion of coal encompasses the finely dispersed particles that ascend with the flue gases The ash which accumulates at the bottom is referred to as bottom ash Prior to venting through the chimneys of coalfired power plants Fly Ash is diligently captured by electrostatic precipitators and other particle filtration equipment When combined with bottom ash extracted from the furnaces base it collectively assumes the nomenclature of coal ash The specification of Fly Ash varies significantly contingent upon the coal type in use however it consistently contains notable quantities of silicon dioxide and calcium oxide CaO both intrinsic constituents of numerous coalbearing rock strata Our establishment headquartered in India boasts a distinguished reputation as a Fly Ash Exporter catering to diverse sectors including cement ready mix concrete steel refractories and the construction industry
Prominent Applications of Fly Ash encompass
1 Manufacture of Portland Pozzolanic Cement Performance Enhancement in Ordinary Portland Cement OPC
2 Partial Replacement of OPC in Cement Concrete
3 HighVolume Fly Ash Concrete
4 RollerCompacted Concrete Employed in Dam and Pavement Construction
5 Production of Ash Bricks and Other Building Materials
6 Construction of Road Embankments Structural Fills and LowLying Area Development
7 Utilization as a Soil Amendment in Agriculture and Wasteland Development
Fly Ash can be categorized into two types based on the coal used
Class F Fly Ash This type results from the combustion of anthracite and bituminous coal Class F Fly Ash typically contains lower levels of lime usually under 15 percent but higher proportions of silica alumina and iron exceeding 70 percent
Class C Fly Ash Produced by burning lignite or subbituminous coal Class C Fly Ash exhibits selfcementing properties It often possesses a higher lime content frequently exceeding 15 percent and sometimes reaching as high as 30 percent This elevated CaO content contributes to the distinctive selfhardening attributes of Class C Fly Ash
Both Class F and Class C Fly Ash are outcomes of coal combustion in largescale power plants Following collection in electrostatic precipitators or baghouses Fly Ash is transferred to substantial silos for distribution To ensure consistency and quality Fly Ash is classified according to precise particle size specifications when required
