Fly ash also names as fly ash or coal ash. As it�??s known to all, fly ash has wide application. However, the wide range of fly ash uses also increases the risks of environmental pollution. The usual pollution contains groundwater contamination and air pollution. Therefore, it is important to store fly ash to prevent it from polluting environment. Steel silo is one of the good choices for fly ash storage. And flyer steel silo deserves your first choice if you decide to store fly ash in silo.
Look forward to coorperate with you.
An essential input for construction, fly ash is witnessing a sharp rise in demand throughout India and Bangladesh. Falcon International is a renowned supplier of this foundation material. We deal with F grade fly ash that is fully checked under various parameters to ensure superior quality. The powdered building material has high combustion rating with the following features:

Fly ash, also known as flue-ash is a residue which is generated during combustion and consists of fine particles. There are impurities in coal which mostly consist of clays, limestone and dolomite particles. These turn up into ash as they cannot be completely burned.
Fly ash is useful in a number of ways and is one of the most researched upon mineral source. It is mainly a pozzolanic substance which contains aluminum and silicon material which in return due to the presence of water can take form of cement.
A lot of research and development initiative have been taken place across the globe to build and develop technologies that can utilize the full potential of fly ash. Royal Mineral takes care to ensure flawless production stages.
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, powdery byproduct produced form burning pulverized coal in thermal power plants for producing electricity. It primarily consists of silica, alumina and iron oxide. Due to its pozzolanic properties. Fly ash is widely used in making concrete, blocks, bricks, and road base materials. It enhances workability, durability, and reduce water consumption. Using fly ash helps in waste management and reduces pollution.
Applications
Fly Ash used as a Pozzolana in Cement, Cement Mortar and Concrete and as an admixture in Mortar and Concrete/ as a part of cement replacement.
1) Cement Production
2) Ready Mix Concrete
3) Self- Compacting Concrete
4) Mass Concrete
5) Roller Compacted Concrete
6) Lightweight Concrete
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 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.

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.
