Stone crusher dust can be used in concrete without significant difference in strength and workability compared to concrete with natural sand. ... Th e addition of 60% Quarry sand replacement in natural fine aggregate shows the improved mechanical properties of concrete. 5. REFERENCES ¾ 1. S. Rajendra Prasad Professor,
The test results shows that the replacement fine aggregate by crusher dust up to 50% by weight has a negligible effect on the reduction of any physical and mechanical properties
1. Stone Dust in Concrete: Effect on Compressive Strength: Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve the quality of concrete but also conserve the natural river sand for future generations.
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, …
strength of replacement of sand with quarry dust of mortar cube (CM 1:1) is higher than the controlled cement mortar cube. The 56 days maximum Compressive strength, split tensile strength and modulus of elasticity of concrete for replacement of sand with quarry dust of 400 kg/m3 at F/C=0.6, was higher than the reference concrete.
Quarry dust is produced from crusher unit and each crusher unit is produced nearly 22% to 27% of dust. This dust is completely waste material for crusher unit but quarry dust is useful for construction work as sand. If we mix quarry dust in sand then only 65% to 75% of sand replaced by quarry dust because strength of concrete is
This paper presents the comparative result of compressive strength and workability of concrete by partial or full replacement of natural sand by crusher dust, in this study two basic mixers (M-20 ...
In the modern world, there is a shortage of River occurred fine aggregate (river sand), and industrialists are disposing of industrial waste inappropriately and improperly, like fly ash, which has resulted in a ban and lack of approval from the. ... Download Free PDF.
The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm 2 but compressive strengths of 21.5 N/mm 2 and ...
2 Stone dust as a part replacement material of sand in concrete Many researchers have done researches to find out the effect of stone dust to replace part of sand in concrete mixture [9-15]. Sankh at all [15] found that many alternative materials such as copper slag, ground granulated blast furnage slag (ggbs), washed bottom ash, quarry dust
Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in …
decreases as the percentage of crusher dust increases. This reflects as percentage of crusher dust increases the water requirement increases and thus slump value decreases which may due texture of crusher dust. Generally crusher dust has rough texture than sand. The aggregate having rough texture requires more water for surface Weighting.
However, the crusher dust results do provide a useful indication of the success of the sand manufacturing process through the sand characterisation and the fresh concrete …
grades of concrete by replacement of sand with quarry dust. Key Words: Concrete, Compressive strength, Quarry Dust, Replacement, Sand. 1. INTRODUCTION Quarry dust, is a by-product releases from the cutting and crushing process of stone which is a concentrated material to use as fine aggregates. By exploding mountain, rock will be …
However, the crusher dust results do provide a useful indication of the success of the sand manufacturing process through the sand characterisation and the fresh concrete workability results. Fine aggregate test results Figures 1-4 show the particle size distributions for manufactured sands and the corresponding crusher dust 0-4 mm fractions ...
1. Maximum increase in compressive strength of concrete occurs at 10% of replacement of sand with crusher dust. 2. It results in good for environment as a cleaning agent as well as for economy. 3. We can use it for small replacements only because at large replacements it results in reduced strength. REFERNCES [1]. Pareek, S. (2001).
To analyse the effect of crusher dust micro structural study was carried out. Through all these tests it was observed that at 28 days curing, replacement of sand with crusher dust as fine ...

Hence it specifies usage of stone dust in concrete beam as an alternative material for river sand. Similar study made that crusher dust can be used up to 10% for sand replacement in concrete beams [3], [12], [14]. Poor structural ductility of beam constructed with fiber reinforced polymer rebar due to failure of beam by brittle failure [15].
It was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22% and it was also found that amongst all the …
1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%. It was also found that …
