Hence, partial replacement of cement becomes a necessity as well as natural sand in concrete by waste material or by-product without compromising the quality of the end product. Partial replacement with Ground Granulated Blast furnace Slag (GGBS), Fly Ash (PFA), Silica Fumes (SILICA) incorporates with of Quarry Dust (QD) as sand replacement.
"F" represents the Fly ash "20" represents the percentage of fly ash. In the second set of trials F.A. i.e. Natural River sand was replaced by 50% with Crushed Rock fines (Quarry dust) the trial were repeated as explained before. If dust is being used in the mix then the designation of the mix will be "D 400 F 20".
Index terms - concrete, quarry dust, class C fly ash, compressive strength. _____ I. INTRODUCTION The fly ash is the mostly used cementitious material in concrete.

the fine aggregate is sand or quarry dust, which the size ranges between 0.15mm and 2.36mm. The mineral filler normally used is quarry dust, 85 percent of which passes the 0.075mm sieve. The aggregate mixture is bound together with bitumen. To replace quarry dust with fly ash firstly, the physical properties were examined, to check samples
40% of fly ash and 50% of quarry dust and billet scale were used. For series D, 5% of cement, 70% of fly ash and 25% of quarry dust and billet scale were investigated in this paper. Mix design in this paper was done based on previous works . The quarry dust (QD) and cement (C) were firstly placed in a mixer and dry mixed for 2 minutes.
30% of fly ash which is maintained at constant (from literature review) and fine aggregate is replaced by varying proportions such as 0%, 20%, 40%, 60%, 80% and in conventional mix. Properties of these fly ash and quarry dust were studied by casting samples using this fly ash and quarry dust.
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 ...

Quarry dust and fly ash worked harmoniously in the production of the geopolymer adhesive mortar. Although silica sand replacement did not cause significant differences on the physical and mechanical properties, it resulted in some improvement in the properties of the mortars. •
dust leads to a reduction in the workability of concrete. Therefore, concurrent use of fly ash and quarry dust in concrete will make the concrete by using their properties in a beneficial way. The decrease in early strength by the addition of fly ash is compensated by addition of quarry dust .The decrease in workability by the addition of
Fly ash, Hydrated lime, Quarry dust and gypsum are manually fed into a pan mixer where water is added in the required proportion for intimate mixing. The proportion of the raw material is generally in the ratio depending upon the quality of raw materials.
From the results of the experimental study, the following conclusions were drawn on concrete when quarry dust and fly ash are added in different proportions. 1) With the addition of 15% of fly ash and 15% of quarry dust the compressive strength increases to 22% then control mix M40 grade at 28 days.
Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age.
