replacement of fine aggregate with stone dust is adaptable (Franklin et al., 2014). 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 mixes, the highest compressive strength was ... Mix Design of the Referral Concrete - M-25 ...
The results of the tests show that stone dust may be utilized in concrete as a partial replacement for fine aggregate. The finding has been made that using stone dust increases the flexural and compressive strength of concrete. The percentage of fine aggregate replaced by stone dust (0, 20, 50, 80, and 100 percent) is explored.
From their Reddy, M.V. (2010) carried out some research, they have concluded that optimum experiments using waste product like stone percent of replacement of fine aggregate by dust and ceramic scrap as partial and full stone dust is 60%.Replacement of 60% of fine prepared six samples of concrete in which first aggregate by stone dust …

Ilangovan et al.4 (2008) reported that the strength of quarry rock dust concrete was comparably 10-12% more than that of similar mix of conventional concrete. Hameed and Sekar5 (2009) studied the effect of crushed stone dust as fine dust and found that flexural strength increases than the concrete with natural sand but the values
This experimental study explores in detail the crushed stone dust which is locally available industrial solid waste material in India as alternative material to natural …
Quarry dust is a waste from the stone crushing unit accounts 25% of the final product from stone crushing unit. ... Design mix of M25grade concrete with replacement of 0%, 20%, 25%, 30%, and 35% of quarry dust organized as M1, M2, M3, M4 and M5 respectively have been considered for laboratory analysis viz. slump test, compaction factor test ...

Results showed that by replacing 50% of fine aggregate with quarry dust, concrete of maximum compressive strength can be produced as compared to all other replacement levels. The effect of quarry ...
Quarry dust has been used for various activities in the construction industry especially for road construction 1. Non availability of sand at reasonable cost as fine aggregate in cement concrete for …
For M20 grade, 25% is the optimum percentage of stone dust mix with the concrete. 30% of stone dust requires relative high cement content. If 50% replacement of sand 450 kg per meter cube cement needed to achieve the target means strength for M25 grade. Also, the increase in water-cement ratio didn't yield a positive result.
To accomplish this specimen were cast for different replacement level at an interval of 10 percent to determine workability and compressive strength of concrete at different level …
While using crushed stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013). It …
The physical and chemical properties of stone dust are within the ASTM standard limits for fine aggregate used in cement concrete. The slump values of fresh concrete range between 27 and 74 mm for ...
The influence of rock dust as a replacement of fine aggregates on cementitious composites was analyzed and evaluated. In this assessment and review, …
The test results indicate that stone dust can be effectively used in partial replacement of fine aggregate in concrete. It is found …
replacement of fine aggregate replacements varies as 0,25,50,75% of riversand. The study explains that quarry dust has required properties of fine aggregate and 50% of quarry dust can be replaced in sand to produce optimum strength of concrete. 25% replacement of quarrydust with fine aggregate gives same strength values as control mix
