- Source: Produced from the combustion of younger lignite or sub- bituminous coals.
- Composition: Contains a high percentage of calcium oxide (CaO), typically more than 20%. It also includes silica, alumina, and iron oxide.
- Properties: Exhibits both pozzolanic and self-cementing properties. The high lime content allows it to harden and gain strength independently when mixed with water.
- Key uses: Used in concrete when early-stage strength development is needed. Its self-cementing properties can allow for a partial replacement of cement in a concrete mix.
- Source: Derived from the combustion of harder, older anthracite or bituminous coals.
- Composition: Primarily composed of silica (silicon dioxide, SiO2), alumina (aluminum oxide, Al2O3), and iron oxide (Fe2O3). It has a low calcium content, typically less than 10%.
- Properties: Possesses pozzolanic properties, meaning it requires a cementing agent like hydrated lime or Portland cement to react with water and form a cementitious compound. It has no self-cementing properties on its own.
- Key uses: Used in concrete to increase its long-term strength, reduce permeability, and enhance resistance to sulfate attacks.

Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries.
The Major Utilization Areas Of Fly Ash :
- Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC).
- Part replacement of OPC in cement concrete.
- High volume Fly Ash concrete.
- Roller Compacted Concrete used for dam & pavement construction.
- Manufacture of ash bricks and other building products.
- Construction of road embankments, structural fills, low lying area development.
- As a soil amender in agriculture and wasteland development.
Types of Fly Ash:
- According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties.
- Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product.
- Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash.
- Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics.
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.
fly ash has a wide variety of applications and uses, though it is primarily known for improving the durability and workability of concrete mixes. Fly ash is also a 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.
Coal Fly Ash
CFA could be used in huge quantities in two areas: ash dyke construction and low-lying region filling [26,27,28]. In several affluent countries, CFA has been utilized successfully as a structural filler.
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 one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. Ash which does not rise is termed bottom ash. In an industrial context, fly ash usually refers to ash produced during combustion of coal. Fly ash is generally captured by electrostatic precipitators or other particle filtration equipments before the flue gases reach the chimneys of coal-fired power plants, and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), being endemic ingredients in many coal-bearing rock strata.
Advantages to Fly ash
Greater long term strength
Improve Workability
Excellent Thermal Insulation
Reduce Permeability
Low heat of hydration
Increased sulphate resistance
Increased corrosion resistance
Reduced Alkali - Aggregate Reaction
Fly ash is very good resource material. It can advantageously used in cement and concrete works as well as fill applications. Flyash is transported to fly ash storage silo. Fly ash is loaded in close tankers and transported to RMC plants. Fly ash is also available in bags.
Portland cement when mixed with water produce cementitious material in this process free lime is also liberated. This free lime cause of porosity in concrete, however if fly ash available in the mix, free lime will reacts with fly ash to produce additional cementitious materials which produce additional strength and make the concrete denser, thus increase its durability, the present of fly ash also helps reducing heat of hydration.

Palm Bunch Ash has long been known to be an excellent source of nature potash fertilizer. Potassium (K2O) also known as Potash, is necessary for the plantâ??s overall health by enabling the various plant processes such as photosynthesis, water movement (stomatic function) and enzyme activity. Sweetness measured by the sugars is dependent upon K2O. Potassium helps increase stalk strength and promotes strong buds.

Product Description :
Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash, being primarily pozzolanic, can actually replace a percentage of the Portland cement, to produce an even stronger, more durable and more environment friendly concrete.
The initial compressive strength is low but as days pass, flyash concrete gains more strength and eventually
has a lot more strenght as compared to normal Portland cement.Significantly reduce the release of CO2 in
atmosphere.Can be used for construction of structure above/under water
