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.
Features Of Fly Ash 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 finely divided residue made from the combustion of pulverized coal that can be used to increase concrete durability and workability, while reducing permeability. As fly ash contains aluminous and siliceous components, it may form cement when mixed with water if the calcium content of the fly ash is high enough. Similarly, mixing fly ash with lime and water can create a substance similar to Portland cement. Fly ash can be separated into two main types, known as: Class F Class F fly ash contains particles covered in a type of melted glass allowing it to reduce the risk of concrete expansion and increase resistance to sulfates and alkali-aggregate reactions. Class C Class C fly ash contains a higher percentage of calcium oxide, making it more effective in strengthening structural concrete. Applications & Benefits of Fly Ash: Fly ash is used in commercial and industrial sectors for improving the durability and workability of concrete mixes. Fly ash is also used as 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.

Fly Ash: 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. Minimum Order Quantity : 1 container
