The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and .

the percentage of fly ash and cow dung ash increases in concrete. It also shows that the standard consistency and initial final setting time increased as the percentage of fly ash and cow dung ash increases in the concrete. Keywords – Fly ash, Cow dung ash, Quarry dust, Concrete, Enviroment.
Fly ash is a byproduct of coal combustion in electric power plants. It's the very fine ash recovered from exhaust gases by emission-control systems. Fly ash is a pozzolan, virtually identical to volcanic ash. When used in concrete mixes, fly ash is known as a supplementary cementing material, or SCM.
The study presented in this paper shows that fly ash can partially replace sand in cement concretes. This type of fly ash concrete has a lower density and manufacturing cost, a reduced coarse .
In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete.
Fly Ash in Portland Cement Concrete. Overview. Fly ash is used in concrete admixtures to enhance the performance of concrete. Portland cement contains about 65 percent lime. Some of this lime becomes free and available during the hydration process. When fly ash is present with free lime, it reacts chemically to form additional cementitious .
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.

Jul 12, 2018 · Making concrete, which is used for roads, bridges, buildings, runways, sidewalks, and a variety of other infrastructure projects, means combining cement with sand and gravel.
inclusion of fly ash into the quarry sand concrete in which it resulted in the enhanced strength at almost all conditions. It can be concluded that quarry sand can be utilized as partial replacement material to natural sand in the presence of fly ash and rice husk ash to produce concretes with fair ranges of compressive strength.
