quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios. that quarry waste fine aggregate had more materials coarser than 1.18, 2.36 and 4.75 mm sieve sizes. Also, higher fractions finer than 150 and 300 µm sieves were present. But the net result was Table1: Chemical composition of quarry dust and fine aggregate Constituent Quarry Dust (%) Natural Sand (%) SiO2 62.48 80.78 Al2O3 18.72 10.52 Fe2O3 6.54 1.75 CaO 4.83 3.21 MgO 2.56 0.77 Na2O Nil 1.37 K2O 3.18 1.23 TiO2 1.21 Nil Loss on ignition 0.48 0.37 4.4 Cement OPC 53 grade conforming to IS: 8112-1989 is used. 2017-2-2 Quarry waste fine aggregate was used in presence of silica fume. The overall test results revealed that quarry waste fine aggregate can be utilized in concrete mixtures as a good substitute of natural sand. It is found that the compressive, flexural strength and durability studies of concrete made of Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 4.75mm. Partial Replacement of Sand by Quarry Dust as fine aggregate ratio Th e utilization of Quarry dust as a partial replacement of sand in concrete can reduce . partial replacement of aggregates in concrete ppt. partial replacement of aggregates in concrete ppt Study of Concrete Involving Use of Waste Paper Study of Concrete Involving Use of Waste Then the cleaned quarry waste was used as concrete fine aggregate. Size distributions of all concrete constituents were analyzed, and workability and compressive strength of concrete were determined to evaluate gradation effect of cleaned quarry waste to improve size distributions of concrete constituents, thus improving concrete properties. 2017-3-30 as fine aggregate in concrete. For the past two years, the escalation in cost of sand due to administrative restrictions in India, demands comparatively greater cost at around two to three times the cost for crusher waste even in places where river sand is available nearby. The function of the fine aggregate is to assist in producing 2001-3-3 3. To prove that the industrial waste from china clay industries can be a replacement for fine aggregate. 4. To study the physical and chemical properties of industrial waste and are the ingredients in concrete. 5. To replace the fine aggregate by industrial waste in different ratio such as 10%, 20%, 30%, 40%, and 50% in M30 mix concrete 6. lateritic sand and quarry dust as complete replacement for conventional river sand fine . concrete in which the fine aggregates are lateritic soils. .. sand aggregate for concrete works as presented in Figure-. 2. .. stabilized lateritic soils.
