Fly ash Wikipedia

Fly ash often replaces up to 30% by mass of Portland cement, but can be used in higher dosages in certain applications. In some cases, fly ash can add to the concrete's final strength and increase its chemical resistance and durability. Fly ash can significantly improve the workability of concrete.

Fly Ash Topic concrete

Fly ash is a by-product from the combustion of pulverized coal, and is widely used as an ingredient in hydraulic-cement concrete. Because it improves many desirable properties of concrete, it is introduced either as a separately batched material or as a component of blended cement. Fly ash reacts with the hydrating hydraulic cement to form a

Recovery, processing, and usage of wet-stored fly

Strategies for the recovery of wet-stored fly ash for use in concrete are different from the processing of dry fly ash. Typically, these are single-process steps, such as air classification to increase fineness, or electrostatic separation to reduce LOI. The recovery of ash from a stockpile or pond is closer to a mining or quarry operation.
