Rock dust is a byproduct of the quarrying industry and results from rock crushing. In the industry it is known as blue metal, cracker or crusher dust. Landscapers use rock dust for filling holes, bedding paving stones and mixing with cement. More recently its applications have broadened to other areas and its true importance is becoming apparent.
With observation of 20% of quarry dust (7 days), the average compressive strength is 29.62 N/mm 2 whereas that for natural sand is 28.44 N/mm 2. For 25% quarry dust, the value increased to 30.81 N/mm 2. Finally, for 30% quarry dust, the strength increased to 32.88 N/mm 2.
Sand is ultimately a much safer option than stone dust for paving projects. However, this is not a black-or-white issue. You may choose to use stone dust if you have a large supply of it, or prefer the texture and appearance of it.

Of course metal is always better than wood and cement is ok for that and a little rebar doesn't hurt, but I only use cement on something that is big, tall and heavy. All other metal posts for corner bracing and line bracing get plain ol sand. Just pour it in the hole and you will have nothing.
Crushed stone is made from rocks that have been broken down by machines called crushers, giving the stones more angular surfaces. This material is produced rather than formed naturally and comes in a variety of sizes ranging from stone dust or screenings to about 12" or larger in diameter.
It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%. It was also found that amongst all
