III. EXPERIMENTAL INVESTIGATIONS A. Mix Proportioning The M30 mix proportion used by weight and w/c ratio is fixed according to the slump of 25 to 50mm. For this concrete mix, quarry dust is added for replacement of sand at 50%, fly ash replacement of cement 20% and plastic aggregate replacement in natural coarse aggregate by step of 5%.
This study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The watercement ratio and mix ratio selected for the experimental investigation were and 1:2:4, respectively. The specimens were cured for 7, 14, 21 and 28 days. Slump, density and compressive strength tests were carried out.
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to 100 % 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 .
The flexural strength of concrete made with quarry dust as fine aggregate is higher (about %) than conventional river sand concrete. 2. The 10–15% rule of thumb was found to be applicable in the estimation of flexural strength of quarrysand concrete based on its compressive strength.

Oct 25, 2017· From this experimental result it is obtained that the 40% of sand replaced by quarry dust in concrete gives the maximum strength and then the strength reduces from 50% replacement of sand.
50% replacement of sand by quarry dust gives higher compressive strength than natural sand concrete. Key Words: Concrete, quarry dust, river sand, compressive strength, replacement. The motive of this study is to determine the effect of quarry dust in concrete as fine aggregate to finding an
This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete. Attempts have been made to study the properties of concrete and to investigate some properties of Quarry Dust the suitability of those properties to enable them to be used as partial replacement materials for sand in concrete.

Use of Quarry Dust to Replace Sand in Concrete ... EXPERIMENTAL INVESTIGATION A. Mix proportioning ... were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand .
The consumption of natural resources like sand and stones for concrete production has resulted not only in their scarcity but also in environmental degradation associated with their extraction, and air pollution due to the generated quarry dust as result of the rock crushing. Also, with increase of mining sites in Rwanda, the amount of mine tailings has extremely increased, and their dumping ...
Recent Trends in Replacement of Natural Sand With ... alternative material to natural sand. Some alternatives materials have already been used as a replacement of natural sand such as flyash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].
maximum content of quarry dust partial replacement of cement in concrete. The percentages of quarry dust partial replacement of cement in concrete are 0, 10%, 15%, 20%, 25%, 30%, 35%, and 40%. M20, M30, M40 grade concrete cubes of 150x150x150mm size were cast for conducting compressive strength test.
