Fly Ash, Slag, Silica Fume, and Natural Pozzolans, Chapter 3
Fly ash is used in about 50% of ready mixed concrete (PCA 2000). Class F fly ash is often used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash is used at dosages of 15% to 40% by mass of cementitious material. Dosage varies with the reactivity of the ash and the desired effects on the concrete (Helmuth 1987 and
Fly ash: Types, Properties, Advantages Disadvantages
Fly ash is a microscopically partitioned residue of thin coal combustion, it is carried by groove gases and collected by electrostatic precipitates, particularly used to make high strength concrete and high performance concrete.. Flyash increases strength, decreases permeability, reduces corrosion of strong steel, increases sulfate resistance and reduces alkaliaggregate reaction.
Fly ash
Fly ash is a coal combustion is part of a set of products that makes up the most abundant waste materials worldwide. If not collected, this waste material is blown out with the flue gas in a coal fired power ash exists after combustion because ash adheres to coal, making up between 115% of its weight. About 90% of the ash is fly ash, while 10% is bottom ash.

What is the use of fly ash in concrete?
Answer (1 of 19): It is produced from the burning of pulverized coal in thermal power plants, the residue is a fine particle which gets carried by flue gases and are collected using electrostatic precipitators. Giving statistics will make you understand the mammoth importance of fly ash in concr...
Ash Handling System of a Thermal Power Plant
· Fly Ash Handling System Fly ash is considered to be collected in ESP Hoppers. Fly ash from electrostatic precipitators or fabric bag filters (or sometimes both), loed at the outlet of the furnace and before the induced draft fan, is extracted by Vacuum Pumps. 9.
Fly Ash | Red Valve
Fly ash is collected through the use of scrubber, or ESP systems (electrostatic precipitators). Dry ash removed by ESP systems is very abrasive due to its small particle size, physical hardness and the sharp edges of the particles. Once fly ash is removed, it is normally stored in some sort of hopper or silo.
