Importance of Gravel and Sand for Concrete Hunker
Sand and gravel in concrete serve several purposes. Because they act as a filler, they also add more volume to the concrete. volume means less air and a stronger product. The size of the gravel also helps to determine the concrete's strength.

Concrete: Scientific Principles
Normally sand, gravel, and crushed stone are used as aggregates to make concrete. The aggregate should be well-graded to improve packing efficiency and minimize the amount of cement paste needed. Also, this makes the concrete more workable.

What Is Bulking Of Sand? And Its Importance [Civil Planets]
If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. For Example, If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3. The reason for that is the moisture content present in the sand makes it a little bulkier.

What is the function of a sand layer underlying paving
The sand layer serves the same purpose of normal blinding layer under concrete structure: (i) Provide a level and flat surface for the paving slab/interlocking blocks to lay on; (ii) Protect the foundation (i.e. underground subgrade and sub-base layer) against adverse outside conditions (e.g. bad weather) during construction of the laying work of paving slab/interlocking blocks.
