stone dust is much better. I''ve used both stone dust and sand and currently I used stone dust for a flagstone patio. The good thing about stone dust is that no weeds grow through it and it packs down a lot harder. Almost like cement. They do have special sand that allows no weeds as well but its more expensive than stone dust.

quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios.

Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.

There are several deposits of quarry dust around the site, which shows that the aggregate used instead of sand was quarry dust. The ballast at the site was ok. River sand has small sugar-like granules which assist in providing the necessary friction that tightly holds the concrete to the steel which is twisted to give it more grip.
