FLY ASH CONCRETE WHAT ARE THE REASONS FOR ADDING FLY ASH

Chemically, fly ash is a pozzolan. When mixed with lime (calcium hydroxide), pozzolans combine to form cementitious compounds. Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix.

The Disadvantages of Fly Ash in Concrete Hunker

Fly ash is a byproduct from coal-fired power plants that is frequently used as an admixture in concrete to replace a portion of the Portland cement. Using fly ash in concrete is environmentally beneficial because it reduces the Portland cement (a major contributor of CO2) required in concrete.

Influence of quarry sand on the properties of high

sand with quarry sand reduces the slump value by 39percent. However, the addition of fly ash in concrete improves the workability. Hence, a judicious selection of the quantity of fly ash and plasticizer can improve the drawback of the reduced workability of concrete due to the presence of quarry sand in concrete.
