Concrete is the most used construction material having basic ingredients as binding material, fine aggregate, coarse aggregate and water in predetermined proportion all the ingredients are homogeneously mixed to obtain resulting mixed of desired
Use of quarry dust as a fine aggregate in concrete draws serious attention of researchers and investigators. ud Therefore, this study is the use of quarry dust, which is inert material or waste that is not useful, as a substitute for sand in concrete.
Experimental programme was conducted using 30%, 40%, 50%, 60% and 70% partial replacement of fine aggregate with stone dust has been taken for concrete of M25 grade with 0.46 water cement ratio.
The research focuses on the effect of using waste marble powder and quarry dust as partial sand replacement materials on concrete properties. Massive exploitation of the nonrenewable natural resources to fulfill the aggregate requirement of billions of tones each year for concrete production bears the serious risk of their gradual depletion.

The. choice of. quarry dust. as . replacement . for sand . has been su. p. por. t-ed in the pr. e. vious study (Manassa, 2010)  showing that up to 20% of sand has been effectively replaced by quarry dust in traditional concrete ...
to study the effect of partial replacement of fine aggregates by quarry dust and cement by fly ash on cement concrete. 1.2 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.
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).
In this experimental study, the effect of quarry dust in lightweight foam concrete in terms of compressive strength had been focused. Cubes with dimension of 150 x 150 x 150mm are being considered for this project. Sample with 0% (no quarry dust), 10%, 20%, 30%, 40% of quarry dust in replacement for sand mass were casted. Foam concrete with
From the results, it was observed that the flexural strength of concrete with 25% and quarry dust were respectively 2% and 4.3% higher compared with concrete with no quarry dust.
Jun 06, 2016· Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. Quarry dust replacing sand in. +

Quarry dust has been used for different activities in the construction industry, such as road construction and manufacture of building materials, such as lightweight aggregates, bricks, tiles, and autoclave blocks. Researches have been conducted in different parts of the world, to study the effects of incorporation of quarry dust into concrete.
This paper present a report on the possibility of developing high performance concrete (HPC) using quarry dust as part of fine aggregates. Quarry dust was used to replace 20% of sand in silica fume-quarry dust (SFQD) and silica fume (SF) concretes. Besides, silica fume was used as 10% replacement of cement in both SF and SFQD concretes.
This study determines the effect of Sulphuric acid on the compressive strength of concrete with Quarry Dust as partial replacement of fine aggregate at 0 %, 15 %, 25 % and 35 %. A total of seventy-two (72) 100 mm cubes were cast and cured in water up to 28 days. The Compressive strength test was done on the first 36 cubes at 7, 14 and 28 days, while the remaining 36 cubes were exposed to 5 % ...
We are investigating the potential of using quarry waste and its effect on the strength and workability of concrete. This paper reports the experimental study which 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).
Large quantity of the quarry dust gets produced annually in the quarries during the extraction of the crushed coarse aggregate. As a result, disposal problems of this material gain significant momentum as these disturb environmental systems also. Now-a-days many of the countries like India is facing problems of ban on the extraction of sand and lacunae in procuring of fine aggregate, which is ...
grade concrete. Control concrete was designed using sand as fine aggregates. Quarry dust concrete was designed by replacement of sand. M15 grade quarry dust concrete were designed with four different water cement ratios and are designated as M15QD(.65), M15QD(.6), M15QD(.55), M15QD(.5) .
Rinse eyes with water if they come into contact with cement dust and consult a physician. Use soap and water to wash off dust to avoid skin damage. Wear a P-, N- or R-95 respirator to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid ingesting cement dust.
Samples of concrete (cubes and cylinders) for one mix, namely 1:1.02:2.22 were made using quarry dust and marble powder as fine aggregate in concrete. INTRODUCTION Currently the world is poised for a major initiative infrastructure development in construction of buildings and other structures where concrete plays a vital role in this initiative ...
May 22, 2017· The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduc...
Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust as substitutes for Natural Sand in concrete. Mix design has been developed for M25 and M40 grades using design approach IS for both conventional concrete and quarry dust concrete.
quarry dust replaced concrete (6). Concrete produced using quarry fines shows improvement in higher flexural strength, abrasion resistance, and unit weight which are very important for reducing corrosion or leaching(7). Self-compacting concrete can also be produced using quarry dust (8). 2 Durability of concrete may be defined as the ability
