Coal Fly Ash Powder
Coal fly ash powder is a fine, powdery material that is produced during the combustion of coal in thermal power plants. It is collected by electrostatic precipitators or baghouses and can be used in various applications.
Coal fly ash powder is mainly composed of silica, alumina, and iron oxide, as well as small amounts of calcium, magnesium, and other trace elements. It can be used as a partial replacement for Portland cement in concrete, due to its pozzolanic properties. When used in concrete, fly ash can improve the strength, durability, and workability of the material, as well as reduce its permeability and heat of hydration.
Coal fly ash powder is also used in the production of construction materials such as bricks, blocks, and roofing tiles. It can improve the strength, durability, and insulation properties of these materials, as well as reduce their environmental impact. We are one of the best Coal Fly Ash Powder Suppliers in India at a low price. Our Coal fly ash powder price is Rs. 3/kg.
In addition, coal fly ash powder can be used as a soil amendment, as it can improve soil structure, water retention, and nutrient availability. It can also be used in the production of ceramics, glass, and other materials, due to its high melting point and pozzolanic properties.
Coal Fly Ash Powder Uses
- Concrete Production: Coal fly ash powder is widely used as a partial replacement for Portland cement in the production of concrete. It can be added to concrete mixes to improve workability, reduce water demand, enhance long-term strength, and increase resistance to chemical attacks.
- Cement and Mortar: Coal fly ash powder can be incorporated into cement and mortar mixes to enhance their performance. It improves workability, reduces shrinkage, and enhances the long-term strength and durability of these materials.
- Stabilization of Soils: Coal fly ash powder is used in soil stabilization applications. When mixed with certain soils, it improves their engineering properties, such as strength, stability, and permeability. This application is commonly used in road construction, embankments, and land reclamation projects.
- Waste Solidification: Coal fly ash powder is utilized in waste solidification processes for the encapsulation and stabilization of hazardous or radioactive waste materials. It helps immobilize harmful substances and enhances the mechanical properties of the treated materials.
- Geopolymer Production: Coal fly ash powder can be used as a raw material in the production of geopolymers, which are inorganic binders that offer high strength, durability, and chemical resistance. Geopolymers find applications in construction, coatings, and other industries.
- Fillers and Extenders: Coal fly ash powder can serve as fillers and extenders in various industrial applications, such as paints, plastics, rubber, and ceramics. It enhances the properties of these materials, such as hardness, strength, and dimensional stability.
Coal Fly Ash Powder Features
- Fine Particle Size: Coal fly ash powder consists of finely divided particles, typically ranging in size from a few microns to several tens of microns. The fine particle size allows for better reactivity and improved performance in different applications.
- Pozzolanic Activity: Coal fly ash powder exhibits pozzolanic properties, similar to other types of fly ash. It reacts with lime in the presence of moisture to form cementitious compounds, contributing to the strength and durability of cementitious materials.
- Chemical Composition: The chemical composition of coal fly ash powder can vary depending on the type of coal burned, combustion conditions, and the collection method. It typically contains silica (SiO2), alumina (Al2O3), iron oxide (Fe2O3), and other minor components such as calcium oxide (CaO), magnesium oxide (MgO), and potassium oxide (K2O).
