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
concrete mixtures. Usually, Quarry Rock Dust is used in large scale in the highways as a surface finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated Elements. Use of Quarry rock dust as a fine aggregate in concrete draws serious attention of
For this concrete mix, quarry dust was added for replacement of sand from 0% to 100% in step of 10%. International Journal of Scientific and Research Publications, Volume 3, Issue 12, December 2013 2 ISSN 2250-3153 www.ijsrp.org B. Casting of specimen Mould of size 150 x
investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.
Quarry dust is an alternate material of sand which is use in construction work. Quarry dust is produced from crusher unit and each crusher unit is produced nearly 22% to 27% of dust. This dust is completely waste material for crusher unit but quarry dust is useful for construction work as sand. If we mix quarry dust in sand then only 65% to 75% of sand

the world, to study the effects of incorporation of quarry dust into concrete. Galetakis and Raka (2004) studied the influence of varying replacement proportion of sand with quarry dust (20, 30 and 40%) on the properties of concrete in both fresh and hardened state (Nevillie, 2002). Saifuddin et
grades of concrete by replacement of sand with quarry dust. Key Words Concrete, Compressive strength, Quarry Dust, Replacement, Sand. 1. INTRODUCTION Quarry dust, is a by-product releases from the cutting and crushing process of stone which is a concentrated material to use as fine aggregates. By exploding mountain, rock will be crushed to
Partial Replacement of Sand with Quarry Dust in Concrete. -The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete.
Jun 06, 2016 Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. It is used as substitute to sand to make quarry dust concrete which is believed to be stronger and more durable than the regular concrete materials. Uses of Quarry Dust. It can be used as substitute to sand wholly or partly.
quarry dust with cement gives the compressive strength of 41.5N/mm2 and after that it goes on decreasing when compared to conventional without any replacement of quarry dust. It is clearly observed that addition of quarry dust up to certain extent will increase the compressive strength of concrete. Er.
increase in quarry dust content. Quarry dust particles absorbed more water as compared to sand and thus negatively impacting the workability of concrete mix. Slump was minimum for the concrete mixture containing 40% quarry dust in place of fine aggregates. The variation of slump with quarry dust content is depicted in Fig. 3.

The quarry dust concrete and river sand concrete shoed slump test values of 80 mm and 60 mm, respectively. And, fresh concrete mix of quarry dust concrete showed lower workability than river sand concrete for 124 mix ratio and water-cement ratio of 0.55. The higher slump interposed for quarry dust may be due to higher sand content in quarry dust.
