analysis shows that there is 40% savings if quarry dust is used instead of sand. [2000] [1] has done a study on replacement of sand by quarry dust in concrete. The compressive strength of concrete with quarry dust has 40% more strength than that of the concrete with sand. M. Shukla and A K Sachan (2000)[2] studied
EXPERIMENTAL INVESTIGATION ON PARTIAL REPLACEMENT OF CEMENT WITH FLY ASH AND QUARRY DUST AS FINE Workability and water absorption Studies were done for concrete with Quarry Rock Dust and compared with the Conventional Fine and coarse aggregate make up the bulk of concrete mixture. Sand, natural gravel and crushed stone are mainly used
Effect of Granite Powder on Strength Properties of as a replacement of sand used in concrete and of granite powder as sand replacement together,Contact Now waste marble powder up to 10% replaced by weight of cement and further addition of waste marble powder was found to decrease the compressive reen Concrete for partial replacement of cement,Granite Powder and Manufactured Sand
This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to in steps of 10%. M20 and M25 grades of concrete were taken for study keeping a constant slump of 60mm. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature. Also the temperature effect on concrete cubes at 100 o C
Concrete of M25 grade was designed for a w/c ratio of for the replacement of 10% coarse aggregate with recycled coarse aggregate and replacement of 50, 60 and 70% of fine aggregate (sand
In this study the properties of concrete with quarry dust as fine aggregate is studied to find out its suitability to replace river sand in structural concrete. Furthermore, use of fly ash with 30% of cement replaced by fly ash is explored as means of increasing the performance of the quarry dust mixes. Quarry dust concrete at the tested water cement ratio is found to have higher compressive
Feb 02 2017 The percentages of quarry dust as partially replacement of cement in concrete ware 0 10 15 20 25 30 35 and the experimental studied 25 of partial replacement of cement with quarry dust improves hardened concrete properties H. S. Sureshchandra et al. have studied on the Effect of Replacement of Sand by
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. Quarry dust, a byproduct from the crushing process during quarrying activities is one of such materials.
12/12/2017#0183;#32;The replacement percentages of Cement with GGBS are 20 %, 40 % and 60 % by weight and 25 %, 50 %, 75 % and 100 % of Quarry Dust are used as a replacement of Natural Sand. Various combination of GGBS and Quarry Dust were prepared using M30 Grade of effect on these replacement materials on Compressive Strength, Split Tensile Strength, Flexural Strength,
satisfy the requirements of sand. 5. Use of quarry dust in concrete help in workability of concrete. 6. Quarry dust is a waste product from stone crushing industry and available almost freeofcost, as partial replacement for river sand.

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 byproduct 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 small size stones and along with this dust
III. EXPERIMENTAL INVESTIGATION A. Mix proportioning Two grades of concrete M20 and M25 having nominal mix proportion of 1::3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.

concrete. NEED FOR INVESTIGATION Quarry Dust These residues are generally less than 1% aggregate production in the normal concrete. The introduction of quarry dust for mixing is limited due to its high fineness. And it is available at low cost and locally available material. It has almost similar properties including texture of river sand, but it has sharp and angular edges. It minimizes
