The suitability of quarry dust as alternative material for the river sand in concrete manufacturing is studied. M25 grade concrete was prepared with 0%, 20%, 40%, 60%, 80% partial replacement of
alternative materials, such as quarry dust, for SCC applications. Results from rheological measurements on pastes and concrete mixes incorporating limestone or quarry dust were compared. It was found that the quarry dust, as supplied, could be used successfully in the production of SCC. However, due to its
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
compressive strength of 100% 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 100% replacement of sand with quarry dust of 400 kg/m3 at F/ C=0.6, was higher than the reference
natural sand replacement in concrete. Concrete results The quarry dust mixes for all of the sands required a higher w/c ratio to achieve an S2 slump than their manufactured sand counterparts. This provides clear evidence of the improved particle shape and grading of the manufactured sand as a result of the V7 process.
quarry dust the concrete produced compared well with normal concrete. He recommended quarry dust for replacement with sand in general concrete structures. Ilangovana et al., [12] studied the strength and durability properties of concrete containing quarry dust as fine
quarry dust. When compared, with the concrete with only river sand, the compressive strength of conventional concrete is 30.15 Mpa while the compressive strength of concrete with 50% replacement of river sand by quarry dust is 31.31 Mpa. Technologies Review, The maximum flexural strength is also at 40% replacement of river sand by quarry dust. .
Concrete used was prepared by replacing 25% and 100% of sand by weight with quarry dust. Also, conventional sand concrete was prepared as reference concrete for comparison. 100 mm cube and 100 × 100 × 500 mm plain beam specimens were prepared using concrete strengths ranging from 25 N/mm 2 to 47 N/mm 2 for the three replacement levels of 0%

Quarry dust is used as partial sand replacement for sand namely as QDC5, QDC10, QDC15, QDC20 and QDC25 for 5%, 10%, 15%, 20% and 25% replacement respectively following normal concrete as OPC. All specimens were tested for compressive strength at the age of 7, 14 and 28 days.
By the experimental investigation, 40% replacement of sand with Quarry dust shows maximum compressive strength and later on, it will decrease after increasing percentage of Quarry Dust in the sand. Workability of concrete decreases as increasing the percentage of Quarry dust; Quarry dust is Waste. If we use quarry dust as a replacement of sand
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 crushed to
After that keeping stone quarry dust amount fix at 10% as sand replacement, PET fiber is added in different percentage (0%, .5%, 1%, and 1.5%) in concrete. Read more Article
Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates. The replacement of river sand with quarry dust enhances the compressive strength of the concrete to a limited extent.
Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively 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 from 0% to 100% in step of 10%.

The project is about replacing sand in concrete production with quarry dust at varying percentage (0%, 25%, 50%, 75% and 100%) to check if the strength matches that of grade MIS with a mix ratio of I :2:4 and also the proportion which has the highest strength. The test carried out includes particle size analysis, slump test, and compressive test.

This work is focused on the use of quarry dust as a total replacement to river sand in the production of concrete, and comparing the results (compressive strength) to that obtained from conventional concrete made with river sand. Key word: Quarry dust, river sand, compressive strength, water cement ratio, workability. 1. INTRODUCTION
Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively 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 from 0% to 100% in step of 10%.
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, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and
This result gives a properties of the concrete materials are tabulated in Table 1. clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength Table 1: Properties of the materials at 50% replacement.

It is observed that the slump value increases with increase in percentage replacement of sand with quarry dust for the same w/c ratio. Concrete does not give adequate
During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared.
