Replace quarry dust ( if necessary ) only with small precentage of fine aggregate. Go through sieve test of quarry dust. Use it only if results are reliable and also sieve out the fine most particals ( having size less than 75 microns) before using. If not removed it will result in creeping Continue Reading Sponsored by Dlubal Software
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.
For the present study, the sand was partially replaced with granite dust by 0, 05, 10, 15, 20, 30 and 40% of its volume.

Stone Dust Stone dust or crusher sand is a type of fine aggregate obtained from stone crushers. Each crusher unit is estimated to produce 15%–20% of stone dust. The stone dust can be used as a soil stabilizer to enhance the geotechnical properties of local soil by replacing the soil with stone dust at various mix proportion [ 32 ].
