Class C Fly Ash Powder

Class C fly ash powder is a type of fly ash that is produced by burning sub-bituminous or lignite coal in power plants. It is a byproduct of the combustion process and is collected from the flue gases by electrostatic precipitators or other mechanical means. We are the leading supplier of Class C fly ash powder in India. and We also provide Class F fly ash powder.

C Grade Fly Ash Powder

Class C fly ash powder is characterized by its high calcium oxide (CaO) content, typically greater than 10%. It also contains silica, alumina, and iron oxide. Because of its chemical composition, Class C fly ash powder is commonly used as a supplementary cementitious material (SCM) in concrete and as a replacement for Portland cement.

When used in concrete, C Grade fly ash powder reacts with calcium hydroxide (Ca(OH)2) in the presence of water to form calcium silicate hydrates (C-S-H), which are the main binding agents in concrete. This results in denser and more durable concrete that is less susceptible to cracking, shrinking, and erosion. Class C fly ash powder can also improve the workability of concrete and reduce its permeability, which enhances its resistance to water and chemicals.

In addition to its use in concrete, Class C fly ash powder can also be used as a soil amendment to improve the fertility and pH of soil. Overall, Class C fly ash powder is a sustainable alternative to traditional cement that can reduce the carbon footprint of construction activities while also improving the performance and durability of concrete structures.

Class C Fly Ash Powder Uses

• Concrete Production: Class C fly ash powder is widely used as a partial replacement for Portland cement in the production of concrete. It can be incorporated into concrete mixes to enhance workability, reduce water demand, improve durability, and reduce the environmental impact of cement production.
• Stabilization and Soil Improvement: Class C fly ash powder is used in soil stabilization and soil improvement applications. It can be mixed with certain soils to improve their engineering properties, such as strength, stability, and permeability. This application is commonly used in road construction, embankments, and land reclamation projects.
• Grout and Mortar: C Grade fly ash powder can be added to grout and mortar mixes to enhance their performance. It improves workability, bond strength, and resistance to shrinkage and cracking.
• Waste Solidification: Class C 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.

Class C Fly Ash Powder Features

• Cementitious Properties: C Grade fly ash powder has inherent cementitious properties due to its high calcium oxide (CaO) content. It reacts with water and calcium hydroxide (lime) to form additional cementitious compounds, contributing to the strength and durability of cementitious materials.
• Fineness: Class C fly ash powder is typically finely ground, with a particle size distribution that falls within a specified range. The fine particle size allows for better reactivity and improved workability when used in concrete mixes.
• Pozzolanic Activity: Class C fly ash powder exhibits strong pozzolanic activity, meaning it can react with lime in the presence of moisture to form cementitious compounds. This reaction contributes to the long-term strength and durability of concrete.
• High Lime Content: Class C fly ash powder contains a higher amount of calcium oxide (CaO) compared to Class F fly ash. The high lime content contributes to its cementitious properties and enhances its reactivity with other components in cementitious materials.

We are one of the best Class C fly ash powder supplier in India. It is important to note that the possessions of Class C fly ash powder may vary depending on the source of the mineral and the processing techniques utilized to make the powder. Therefore, it is necessary to obtain from a reputable Class C fly ash powder supplier who can furnish info on the grade and features of the product.
