Quarry dust, is a result of crushers while doing quarrying activities. Quarry dust was taken from paritala region quarries in Vijayawada. The present research work is planned to study the importance of quarry dust when it is replaced with sand in concrete as partially from various crusher samples. The study mainly involve on compressive strength.EFFECT OF QUARRY DUST AS PARTIAL ,This study examines stone quarry dust in different percentages (5%, 10%, 20%, 30%, 40%). 30%, 40%) as partial replacement of sand.

A quarry is a place where natural stone, gravel or sand is extracted for use in construction or other decorative building purposes (such as gravel paths or decorative garden aggregates). Quarries produce a wide variety of natural stone materials, including limestone, gypsum, marble, sandstone, slate and granite.quarry meaning of quarry in Longman Dictionary of ,quarry.

Quarrying. Imagine thick layers of materials mud, sand, ash, lava, and more laid down over millions of years, new on top of old. Imagine the materials in these layers changed by heat and pressure, and then Study on Compressive Strength of Quarry Dust as Fine,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.An Experimental Study on Usage of Quarry Rock Dust as ,Concrete is the commonly used material in the construction industry. The widely used raw material in the concrete are cement, fine aggregate, coarse aggregate and water, of this common river sand is used as fine aggregate. But, nowadays river sand is at great rate of depletion and expansive, due to which there was a need for an effective alternative.
There is a very high waste factor in the quarrying of dimension stone. For some quarries the amount of usable stone is only 15 to 20 percent of that quarried. For this reason an important aspect of quarry planning is the location of the waste or “grout” pile.

The concept of quarrying has been around since the dawn of civilization, with many different working techniques having been developed. A quarry is typically defined as being a surface excavation for the production of rock as the principal product. As such, it differs from an open cast, opencut, surface or openpit mine in that the rock itselfEffect of quarry rock dust on the flexural strength of ,Portland limestone cement, river sand and quarry rock dust both of 2 mm maximum size as fine aggregate, and 14 mm crushed rock coarse aggregate were used for the concrete The particle size distribution and the physical properties of the fine and coarse aggregates are shown in Fig. 1 and Table 1 respectively.

Definition: Stones occur in the form of natural rock masses or layers on the surface. The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones.. It Quarry Products Perth Menzies Quarries,Menzies Quarries produces sand, rock and gravel products in the Mogumber Quarry which is located 130km north of Perth’s CBD. The licensing of this quarry enables the provision of up to 500,000 tonnes of extracted material annually including road base grave, aggregated stones and crusher dust.
