After that mixing of cement and water, then that fills the air spaces between the coarse aggregate. Sands can also be used in pipe sand or walkways as a levelling medium and pools, patios

Manufactured Sand vs. Natural Sand Concrete, Sand, Stone

Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Well-shaped natural sands are ideal for workability of mixtures.
