SEPPE Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4-0.8 g/cm�³, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
Microsphere cenospheres in thermal insulation coating with powder shape from the coal ash, cementing well
The microspheres are a waste material arising in the process of combustion of hard coal. The product is made of spheres with a diameter of 10-800 microns, filled with gas, mostly CO2 and NO2. Sheaths of the spheres are 0.2-3 microns thick, what makes the microspheres have a great volume at a relatively low gravity. Material contains mainly: silicon oxide (SiO2), aluminum oxide (Al2O3), magnesium oxide (MgO), iron trioxide (Fe2O3), potassium oxide (K2O), calcium oxide (CaO) and vestigial admixtures of other metals.

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 cenospheres glass crystalline hollow microspheres ranging in size from 20-50 to 400-500 microns micrometers produced in furnaces of thermal power plants using coal. Furthermore, we have contracts with several power plants and can supply about 4,000-5,000 tons of goods annually.

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.
