Class F fly ash is designated in ASTM C 618 and originates from anthracite and bituminous coals. It consists mainly of alumina and silica and has a higher LOI than Class C fly ash. Class F fly ash also has a lower calcium content than Class C fly ash. Replacement When used in portland cement, Class F fly ash can be used as a portland cement replacement ranging from 20-30% of the mass of cementitious material. Advantages When used as a portland cement replacement, Class F fly ash offers the following advantages when compared to unmodified portland cement: Increased late compressive strengths (after 28 days) Increased resistance to alkali silica reaction (ASR) Increased resistance to sulfate attack Less heat generation during hydration Increased pore refinement Decreased permeability Decreased water demand Increased workability Decreased cost ($80/ton for portland cement vs. $30/ton for fly ash).

Fly ash is an inexpensive replacement for portland cement used in concrete, while it actually improves strength, segregation, and ease of pumping of the concrete. Fly ash is also used as an ingredient in brick, block, paving, and structural fills. Fly ash can be a cost effective partial substitute for Portland cement in markets that are experiencing supply shortages. An industrial by-product that is otherwise waste, fly ash is environmentally friendly because it is recycled and has low embodied energy. Because fly ash cement requires less water than portland cement, it is easier to use in cold weather. It can be formulated to produce various set times, cold weather resistances, strengths and strength gains, depending on the job. Fly ash can be used sparingly as an admixture or in large amounts to replace portland cement. The material is somewhat lighter than portland cement. 50 Kgs, 1000 Kgs & Bulkers of 20000 Kgs.
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 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.
