Fly ash is a byproduct from burning pulverized coal in electric power generating plants. During combustion, mineral impurities in the coal (clay, feldspar, quartz, and shale) fuse in suspension and float out of the combustion chamber with the exhaust gases.
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 is a by product of coal based thermal power station generated by the combustion of pulverized coal. Fly Ash is a fine, grey amorphous powder, rich in silica & alumina and spherical in shape. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process and the selection process. Therefore, it is important that when considering the use of Fly Ash to look no further than a company with the in depth technical knowledge and support to manufacture and supply a high quality product, that company is KRISHNA ENTERPRISES(DOMESTIC AND INTERNATIONAL TRADE).
"Our Technology means even Better Quality" :
KRISHNA ENTERPRISES(DOMESTIC AND INTERNATIONAL TRADE) only selects Fly Ash that is highly reactive and has water reducing characteristics. Our Fly Ash is amongst the first classified and processed material being made available in India. By classifying and processing, we ensure that a large proportion of our Fly Ash is composed of fine particles, which results in a more controlled and consistent product. Our Fly Ash complies with the stringent International codes of practice such as :
BS EN 450 S, ASTM C 618 Class F and IS 3812 Grade 1
Our customers can therefore be assured of the highest standards of quality, process control and product consistency.

Fly Ash also known as coal ash or Pulverized Flue Ash, is a byproduct of burning coal and comes from the power plant generating electricity from the coal. Fly Ash is a Grey Colored Fine Powder, Rich in Alumina, Iron And silica. It is formed of silt-sized particles and is spherical in shape and its size ranges from 10 to 100 micron. Due to its shape it enhances its workability and fluidity of fresh concreate. It is even finer than lime and Portland cement. When water or lime is added to Fly Ash it forms compound which is similar to Portland Cement. Fly Ash finds its major application in Power Plant Industry followed by Petrochemicals Industry, Steel and Foundry Industry and even in Brick making plants. Jyoti Chemical provided Fly Ash is free from all impurities and pure. It is procured with expertise and has best quality. We are one of the trustworthy supplier of all the grades and types of Fly Ash. Jyoti Chemical provides you with High Grade Fly Ash Powder, Dry Fly Ash and Powdered Fly Ash.
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

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. Class F fly ash also has a lower calcium content than Class C fly ash.
Replacement
When used in portland cement, Class F fly ash can be used as a portland cement replacement ranging from 20-30% of the mass of cementitious material.
Advantages
When used as a portland cement replacement, Class F fly ash offers the following advantages when compared to unmodified portland cement:
Increased late compressive strengths (after 28 days)
Increased resistance to alkali silica reaction (ASR)
Increased resistance to sulfate attack
Less heat generation during hydration
Increased pore refinement
Decreased permeability
Decreased water demand
Increased workability
Decreased cost ($80/ton for portland cement vs. $30/ton for fly ash).
