  • Manufactured Sand vs. Natural Sand - Concrete,

    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.
