observed that by 25% of partial replacement of cement with quarry dust improved hardened concrete properties. Keywords: Quarry dust, cement, water, aggregates. -----***-----1. INTRODUCTION Quarry dust is a waste product obtained from quarrying. It can be used as an effective filler material instead of cement. In the present study, the ...
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.
The DBY of concrete prepared with the partial replacement of cement by quarry dust with 0%, 5%, 10%, 15%, 20%, 25%, 30% and 35% by weight of cement and cubes were immersed in 5% H 2 SO 4 and 5% HCl acid solutions by volume of water.
THE CONCRETE COMPOSITION CAN ALSO BE SUITABLE FOR PARTIAL REPLACEMENT (UP TO 60%). THE FLY ASH,QUARRY ROCK DUST CAN BE USED FORM …
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 by-product from the crushing process during quarrying activities is one of such materials.
Experimental Study on Concrete Using Waste Marble Powder and Quarry Dust as Partial Replacement of Cement and Fine Aggregate D. Suji, K. Kumar Engineering 2016 : Concrete is the most important component used in the construction industry throughout the world, where the fine aggregate is generally natural sand.
The percentages of quarry dust partial replacement of cement in concrete are 0, 10%, 15%, 20%, 25%, 30%, 35%, and 40%. ... This paper deals with the use of CRD as filler …
Replace quarry dust ( if necessary ) only with small precentage of fine aggregate. Go through sieve test of quarry dust. Use it only if results are reliable and also sieve out the fine most particals ( having size less than 75 microns) before using. If not removed it will result in creeping Continue Reading Sponsored by Dlubal Software
concrete mix and quarry dust will be used as a fine aggregate. The gravity quarry dust is replaced by sand varying different percentage (0%, 15%, 30%, 45%, 60% & 75%). then test data of quarry dust concrete will be compared with test data from a standard concrete without quarry dust Keywords: Quarry, water cement ratio, compressive

powder and quarry dust as a partial replacement of cement material. Self-compacting concrete was produced by partially replacing the cement by 10%, 20%, 30% Lime stone and Quarry dust powder, and their influence on fresh properties such as passing and filing ability, flowability are examined as per
Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, …
Ebrahim ( 2018) studied the mechanical behavior of C25 and C30 grade of concrete by partially replacing cement with quarry dust by 5%, 10% 15% and 20% (PPC and OPC). The optimum replacement of cement by quarry dust recorded from the findings was 5% and 10% for PPC and OPC, respectively.

It can also be used as partial replacement of cement in concrete. Cement can be replaced partially by quarry dust in percentage by weight like …
The ingredients of concrete consist of cement, fine aggregate and coarse aggregates, water. When the reaction of water with cement takes place hydration process is done and a hard material is formed. In this project work we used quarry rock dust as a partial replacement of fine aggregate and fly ask replaced by cement.
Three series of concrete mixtures were made. Series I and II with water-cement ratios of 0.70 and 0.53, respectively, consisted of mixtures incorporating 5, IO, 15, and 20 percent limestone dust, whereas Series III with a water-cement ratio of 0.40 covered mixtures containing 10 and 20 percent dust. A control mix was also included in each series.
To produce good quality of concrete the selection of materials as well as selection of required grade of concrete is necessary We have used M25 grade of concrete with the ratio 1:1:2 i.e. 1 part of cement, 1 part of fine aggregate and 2 part of coarse aggregate A.
