It is identified that 40% replacement of sand by quarry dust give good result in strength than normal concrete for M20 and M30 grade. The results possess that 40% replacement of sand by the quarry dust induced higher compressive strength and the workability of concrete decreases as replacement increases.
For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%. International Journal of Scientific and Research Publications, Volume 3, Issue 12, December 2013 2 ISSN 2250-3153 B. Casting of specimen Mould of size 150 x 150 x 150 mm was used to cast specimens ...
Abstract. The production of aggregate for use in concrete production yielded a significant amount of fines fraction during the crushing operation at the quarry. The fines fraction, also widely known as quarry dust (QD), poses environmental risks such as land and air pollution in the absence of a proper disposal channel.
Five alkali-activated concrete mixtures were cast with 0, 10, 20, 30, 40 and 50% of quarry dust. Moreover, the effect of sugarcane bagasse ash as a precursor (10, 20, and 30% SCBA as a replacement of the GGBS) was evaluated for quarry dust aggregates used alkali-activated binder.

cement concrete +quarry dust (M20 & M25). The experimental result showed that the additional of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature.
In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste fine aggregates (dust waste) are generated.
considerable amount of quarry dust is composed. In this analysis, the experiment work is performed by using cement, fine aggregate, coarse aggregate, quarry dust. The …
Quarry dust The basic tests on quarry dust were conducted as per IS-383-1987 and its specific gravity was around 1.95. Wet sieving of quarry dust through a 90 micron sieve …
The use of quarry dust in concrete has shown to improve strength properties and increase the workability of concrete Kapgate and Satone [ 5] and Shakir et al. [ 6 ], investigated the fly ash brick and the incorporation of 50 % quarry dust by weight has significantly improved the compressive strength.
concrete was assessed. Prakash et al [3] assessed the use of dust for normal concrete, reporting that a 40% replacement of fine aggregate by quarry dust resulted in the highest compressive strength. In the study reported by Bahoria et al [4] sand was replaced with quarry dust in combination with waste plastic.

Quarry dust and quarry fines could also be produced as by-products from the quarrying of other rock types. The quarry dust derived from granite quarry is considered the most suitable for use as a constituent raw material in concrete production due to its highly inert chemical nature.
concrete. Quarry dust is a byproduct that is generated from the crushing plants and which is abundantly available to an extent of millions of tons per year associated with disposal problems and serious environmental effects. [1] Mineral aggregate production produces a major amount of
Therefore, the concurrent use of quarry dust and fly ash in concrete will lead to the benefits of using such materials being added and some of the undesirable effects being negated. Quarry dust.
