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 a fine gray powder consisting mostly of spherical, glassy particles that are produced as a byproduct in coal-fired power stations. Fly ash has pozzolanic properties, meaning that it reacts with lime to form cementitious compounds. It is commonly known as a supplementary cementitious material. Fly ash is suitable for a wide variety of applications and uses, including: â?¢ Concrete â?¢ Dams â?¢ Flowable fill â?¢ Mines â?¢ Landfills â?¢ Geopolymer concrete Fly ash is also known as flue-ash or simply ash. Fly ash significantly improves concrete performance and also provides many benefits in cement and non-cement applications. Also, when treated with sodium hydroxide, fly ash appears to function well as a catalyst for converting polyethylene into a substance similar to crude oil in a high-temperature process called pyrolysis.
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.
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 Product: Fly Ash (ASTM C618 CLASS F) Price Of Prodiuct : USD 36--USD 55 PER MT Product Origin : INDIA Key Specifications/Special Features Grade Standard : ASTM618/ BS 3892 Physical State : Powder Colour : light Grey , Grey Usage : Industrial Lead Time : 10-12 Days , Negotiable Minimum Order Size and Packgaing details : MOQ- One 20 ft conatiner Packing: 1.4 Mt Jumbo Bags with Inner Liner, As per client requirement

Fly ash is a burnt and powdery derivative of inorganic mineral matter that generates during the combustion of pulverized coal in the thermal power plant. The burnt ash of the coal contains mostly silica, alumina, calcium, iron are the major chemical constituents. Depends on the burning temperature of coal

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
Fly Ash : 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.
