RK Copper & Alloy LLP is a reputed supplier of high quality fly ash. We supply high-grade products to diverse industries.
What is Fly Ash?
Fly ash is a fine, powdery residue produced during the combustion of pulverized coal in power plants. This mineral-rich byproduct, removed from flue gases through advanced emission control systems like electrostatic precipitators or bag filters is characterized by excellent pozzolanic properties. When fly ash is added to water it reacts with calcium hydroxide to form cementitious compounds which makes it an essential material for the construction and infrastructure sectors.
Features and Applications of Fly Ash
Fly ash has special properties such as it is a spherical particle, fine particle size and uniform chemical composition. These attributes make it very useful across a wide range of engineering applications. It is especially used in Portland cement concrete (PCC) as a pozzolanic material that increases durability, decreases water demand and improves workability. Our fly ash is also used for soil modification, structural fills, flowing fills, grouts and as a mineral filler in hot mix asphalt applications. Due to its environmental friendly nature and availability, it is affordable when used in construction industries.
Whether you’re in construction, infrastructure or industrial sectors, we offer fly ash that are designed to deliver efficiency and sustainability in various applications. Contact us today to know more about our offerings and how we can help make your projects successful.
