Quarry dust has some advantages over river sand such as better contribution to the strength of the cementitious material, better workability, lesser cement consumption and eco-friendly. Published literature report that quarry dust was deployed as fine aggregate to replace natural sand in conventional concrete [25], [26], [27], [28].

With observation of 20% of quarry dust (7 days), the average compressive strength is 29.62 N/mm 2 whereas that for natural sand is 28.44 N/mm 2. For 25% quarry dust, the value increased to 30.81 N/mm 2. Finally, for 30% quarry dust, the strength increased to 32.88 N/mm 2.

Highlights. •. QDP as a replacement of fine aggregate in concrete is effective, economic and sustainable. •. Compressive strength improves up to an …

3.1.6 Quarry Dust Quarry dust, a waste product of the crushing process, is a concentrated material that can be used as aggregates for concreting, particularly as fine aggregates. The rock is crushed into different sizes during quarrying activities; the dust produced during the process is referred to as quarry dust and it is created as trash.

It is well known that adding quarry dust to concrete reduces its workability while increasing its strength when compared to concrete made with the same amount of river sand.

Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 4.75 mm. This paper presents the feasibility of the usage of Quarry Rock Dust as a substitute for Natural Sand in geopolymer mortar. The

The study discusses the effect of quarry dust on the specific gravity, liquid limit, plastic limit, shrinkage limit, compaction characteristics, California bearing ratio, …

Sahu A.K. et al. [17] reported significant increase in compressive strength, modulus of rupture and split tensile strength when 40 percent of sand is replaced by Quarry Rock Dust in concrete.

Rock quarry dust or quarry dust is produced as solid wastes during crushing of rocks to obtain aggregates. This waste product is left in huge heaps in the neighborhood of the quarry causing serious space problems and health hazards. ... California bearing ratio, shear strength unconfined compressive strength, Young's …

wind-blown dust can cause a significant nuisance to residential and commercial neighbours. The most common areas of complaint relate to dust on roofs, walls, windows, paths and gardens, and on residents' cars and washing. Neighbours may contact the quarry directly, but are equally likely to complain to their local authority.

Figure 5 highlights the variation of the MDD with the rock quarry dust content. It can be seen from Fig. 5 that with the increase in the rock quarry dust content from 60 to 80%, the MDD increases significantly and thereafter, the MDD decreases with further increase in the rock quarry dust content from 80 to 90%. Hence, the optimum …

Limestone: A sedimentary rock and the most commonly used rock type for crushed stone in the United States. One of the most versatile rocks for construction, limestone is able to be crushed easily, making it a primary rock used in ready-mix concrete, road construction, and railroads. It is widely available in quarries across the country.

Sivakumar et al., 2011 studied the mechanical properties of cement mortar and concrete by. replacing fine aggregates with quarry dust. They reported a 11.8% increase in compressive. strength of ...

The by-product materials considered are acombination of GGBFS and Fly ash. The experimental program involves casting of geopolymer mortar cubes by using GGBFS, Flyash and Quarry rock dust and testing them at 1 day, 3 days and 7 days for compressive strength. Different parameter considered in this study is alkaline fluid to binder ratio …

At 60:40 ratios of four different quarries sand, the overall strength has increased as 4.3% to16% of that of conventional concrete as shown in fig. 6. Stress-Strain Curve and Young's Modulus of Concrete: The stress- strain curve for all quarries sand and river were plotted in the form of graphs.

Hence shear parameters of rock quarry dust and sand mix are found out at different dry unit weight of the sample by direct shear test. The quarry dust and sand mix were taken with different dry unit weights like 12.17 kN/m 3, 16.71 kN/m 3, and 19.62 kN/m 3 at different strain rates of 0.25 mm/min, 0.625 mm/min, and 1.25 mm/min, respectively ...
