[17] reported that the inclusion of 40% quarry dust did not affect the compressive strength. Similarly, Cheah et al. [18] reported that the inclusion of quarry dust did not affect the
Crushed stone dust can be applied as a substitution to natural sand in cement concrete construction, according to a Batra et al. (2008) study. ... and the fine and coarse aggregates applied in concrete. Maximum concrete compressive and tensile strengths are attained when 40% to 50%, 60%, and 70% of the ordinary sand is …
be read at comparable compactibility ranges. Molding sand at higher or lower compactibility will produce varying green strengths. Green compression in conjunction with moisture can be used to determine the available bond. Permeability Permeability is a test of the venting characteristics of a rammed sand.

You might be interested to know that its name comes from the Greek words for leek-green stone. The lovely green color of this mineral is often produced by irradiating or heat-treating amethyst containing ferrous iron (Fe 2+) at approximately 500°C. However, there have been instances of natural prasiolite being found.
Whereas when the dosage changed to maintain the workability, the slump varied from 60 mm at 0.6% (0% stone dust) to 35 mm at a 2.2% dose ( stone dust), respectively. The 7-day compressive strength of concrete cubes was found to be at its maximum at 50% replacement as compared to all other percentages.
