I read several places that 3/4" crushed stone is "self-compacting". That is, you dump it in a trech (as in under a concrete footing or floor) and you don't have to compact it with a plate compactor - it is already as "compacted" as it needs to be.

By adding 30% marble dust and 70% quarry rock dust in place of Fine aggregate in the concrete, increase in the 28-day compressive strength. As well as workability of concrete is also increased. In addition the 7 day strength also increases, so that formwork can be removed soon. This type of concrete is useful as Self Compacting Concrete(SMC).

The self-compacting concrete differs from conventional concrete in the following three characteristic features, namely, (i) appropriate flowability, (ii) non-segregation, and (iii) no blocking tendency. An increase in the flowability of concrete is known to increase the risk of segregation. Therefore, it is essential to have a proper mix design.

This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially replaced by the SD (<2/3).
