It is identified that 40 replacement of sand by quarry dust give good result in strength than normal concrete for M20 and M30 ...
shortage in many areas. Quarry dust can be used as an economic alternative to the natural sand. In this investigation an attempt is made to utilize quarry dust as a partial substitute for natural sand in producing concrete. Natural sand is replaced by Quarry dust at an interval of 5, 10, 15, 20 and 25. Mix proportions for M 20
In order to study the strength behaviour and fire resistance of the concrete made with full replacement of sand with Quarry stone dust the tests are conducted. Results so obtained for the tests conducted on cubes and prisms for M25 and M40 grades of concrete with various dosages of super plasticiser at 7days and 28 days were tabulated.
Quarry dust for partil replacement of sandFly Ash and Dolomite as partial replacements to cement are used in concrete.. II LITERATURE SURVEY This chapter presents the literature on a short review of the terminology and also the past studies on Dolomite powder, Fly ash, Quarry dust
Partial Replacement of Sand with Quarry Dust in Concrete Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength ...
Dec 01, 2017 The paper presents results of study on concrete using quarry dust to replace sand at levels of 0, 25, and 100 by weight. Design mixes were prepared to achieve concrete grades C25, C30, C35, C40 and C45 for each of the three replacement levels.

The sand availability as a fine aggregate at low cost which needs the reason to search as a alternative material.
Abstract. Abstract--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.
