Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly of silica. Nearly all particles are spherical in shape. Fly ash is a pozzolan, a siliceous material which in the presence of water will react with calcium hydroxide at ordinary temperatures to produce cementitious compounds. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical components present in fly ashes.
Fly ash significantly improves concrete performance in different ways and also provides many benefits in cement and non-cement applications. Fly Ash colour can vary from grey and dark grey, yellowish tan and light to brownish.
ADVANTAGES OF FLY ASH IN CONCRETE
Fly Ash is a Pozzolan
Improves concrete workability and lowers water demand
Sulfate and Alkali Aggregate Resistancet
Rise in compressive strength over time
Environment friendly
CEMENTATION Fly Ash is optimized for its fineness while reducing the water demand and improving the chemical compositions to maximise its benefits when used in concrete. Fly-ash can also be used as an add-on to concrete mixture with pozzolanic and/or latent hydraulic properties.
We at CEMENTATION selectively collect fly ash and subject to rigorous testing, further refines these collected materials to produce quality fly ash products meeting the needs of our customers.
Fly ash is a by-product of coal burning at the utility plants. As coal is burned, non-combustible mineral impurities in coal evaporate andcondense into tiny particles of glass, almost totally spherical inshape. The individual particles are very small, like talcum powderand are carried up and out of the boiler in the flow of exhaust gasesleaving the boiler after the coal is consumed.
The fly ash particlesare removed from the exhaust stream in bag houses or electrostatic precipitators and then stored for later shipment
The difference between fly ash and Portland cement becomes apparentunder a microscope. Fly ash particles are almost totally spherical inshape allowing them to flow and blend freely in mixture. Thatcapability is one of the properties making fly ash adesirable admixture of concrete.
Fly ash is a fine particulate residue generated during the combustion of pulverized coal in thermal power plants. Pulverisation involves grinding coal into a very fine powder to ensure more efficient and complete combustion.
When coal is burned, non-combustible minerals in the fuelâ??such as silica, alumina, and ironâ??melt and fuse into tiny glass-like particles. These particles are carried away with flue gases and are captured using electrostatic precipitators or bag filters, resulting in what is known as fly ash. The material is ideal for use in cement, concrete, AAC blocks, and other construction applications.

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.
