Abstract- 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.
The experiments were done with cubes, reinforced beams, and slabs samples which had 0, 25, 50, and 100 % replacement of sand with quarry dust. Samples of quarry dust concrete with 2-4% of sisal ...
Quarry dust can be used as. an admixture in concrete efficiently to lessen its impact on. environment and human. It can also be used as partial. replacement of cement in concrete. Cement can be ...

Bakhrija quarry is surrounded by a number of stone crushing units (≈ 25 units) around it. ... Simultaneously, addition of the fine dust to soil (dominantly aeolian sand) results in improved water holding capacity and maintaining the neutral pH of better crop yield in case of sandy soil being observed in the region around Bakhrija quarry. The …
With observation of 20% of quarry dust (7 days), the average compressive strength is 29.62 N/mm 2 whereas that for natural sand is 28.44 N/mm 2. For 25% quarry dust, the value increased to …
The quarry dust has been used as a partial replacement for cement proportion at different levels of replacement (25%, 30% and 35%). Quarry dust was used as the main material in this project to measure the effectiveness of concrete performance. In this research, the quarry dust composition was determined by using X-Ray …
