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 Resistance
- 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 the 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.
CEMENTATION supply capacity more than 216,000 TPA of material in Asia, Middle East & Africa and across India. Our Fly Ash bagging unit is located very close to Mundra port, our facilities include in-house container loading throughout a year and huge warehouse to store cargo.
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, baghouses, or mechanical collection devices such as cyclones. Fly ash is commonly used in the production of concrete. It is applied as a supplementary cementing material.
The research methodology used to estimate and forecast the fly ash market involves obtaining data on key vendor revenues through secondary research (annual reports, press releases & investor presentations of companies, white papers, solvent journals, certified publications & articles from recognized authors, authenticated directories, and databases). Vendor offerings are also taken into consideration to determine market segmentation.
