River sand is most commonly used fine aggregate in concrete but due to acute shortage in many areas, availability, cost environmental impact are the major concern. To overcome from this crisis, partial/full replacement of sand with quarry dust can be an economic alternative.
Nowadays recycling of waste and industrial by products gaining popularity to make concrete environment friendly material and the concrete can be called as Green Concrete. This review paper will give us a brief idea about as well as advantages and disadvantages about green concrete.
Stone, Sand and Gravel Review July/August 2010 (Page 26) Using Quarry Fines for Sustainable Construction Q uarry processes such as blasting, crushing and screening of coarser grade aggregates produce byproduct mineral fine materials, commonly known as quarry fines or quarry dust. Quarry fines are typically less than 5 mm in size and consist of coarse, medium and fine sand particles, and a .
Literature Review the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is he suitability of quarry dust as a sand replacement material formed as waste.
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 researchers and investigators.
compressive strength was found to be maximum at 30% (/mm2) replacement of fine aggregate by industrial waste which was greater than the conventional concrete. The compressive strength reduced beyond 30% replacement. Thus it is evident that fine aggregate can be replaced by the waste material from china clay industries up to 30%.
Behaviour of Concrete on Replacement of Sand with Quaries Stone Dust as Fine Aggregate A. Suribabu 1, Dr 2, Ravindra Krishna 3 Student, Department of Civil Engineering, of Engineering and Technology, Bhimavaram, India
possibility to replace one hundred percent of the fine aggregate (sand) with quarry rock dust in the concrete mix that will resulted in an increase in the compressive strength of around 10% 12%, as well as the durability of quarry rock dust concrete under sulphate and acid attack is higher than that of the conventional concrete.

waste. One possible source of construction aggregate is sand that has been manufactured from the surplus material (crusher dust) that results when coarse aggregate is produced in hard rock quarries. Coarse aggregate production typically yields 25% to 45% crusher dust depending on the parent rock, crushing equipment and crushing conditions [2].
2. Literature Review The suitability of quarry dust as a sand replacement material shows that the mechanical properties are improved and also elastic modulus. The compressive strength achieved optimum by replacing fine aggregate with quarry dust in ratio of 60 : 40 as done by Hmaid Mir [1].

Introduction. Only insignificant quantities have been utilized and the rest has been dumped unscrupulously resulting in environment problem. In the present work, it is aimed at developing a new building material from the granite scrap, an industrial waste as .
A central composite design (with 2*2=4 factorial points, 2*2 starpoints and 2 repetitions of central point) was adopted to optimize and model the effect of water/cement ratio (), and walnut shells content () wt.% for concrete mixes used walnut shell for partial replacement of fine aggregate.
Know the details of M Sand vs River or Natural Sand. Manufactured sand is a perfect substitute for river sand. These blog covers full details of msand advantages. Impurities and wastage is almost nil.
quarry dust is reduced by the addition fly ash. This paper investigates the workability and strength characteristics of Quarry Dust Concrete (QDC) containing 0% to 30% of fly ash. Based on the test results, it can be concluded that combined use of quarry dust and fly ash can be shown improved strength in concrete and also
1. While using waste glass as fine aggregate replacement, 28 d strength is found to marginally increase up to 20% replacement 2. Marginal decrease in strength is observed at 30 to 40% replacement level of waste glass with fine aggregate. 3. Waste glass .
Glass fine aggregate 0 108 143 178 211 278 Material preparation Coarse and Fine Aggregate The aggregates used in this project were sourced from Australian suppliers and were readily available in the country. The coarse aggregate was of angular nature and originated from Anakie quarry, with a nominal maximum aggregate size of 19 mm.
and fine aggregate replaced up to 40% by quarry dust by conducting following tests like compressive strength test and splitting tensile strength test and the strength was observed greater than the target mean strength. 2.

Thus indicating the possibility of using quarry dust and saw dust as a partial replacement of fine aggregate up to this level. The weight can be reduced upto 20%.
Crusher dust considered to be a solid waste material posing a serious disposal problem is utilized as full replacement material for sand in brick masonry works. Further, the micro fines below 150 micron size, presenting in the crusher dust are removed by sieving and micro fine free crusher dust is used as the alternative to sand. Three
