  • Manufactured Sand vs. Natural Sand Concrete, Sand, Stone

    The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. 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.Aggregates CEMEX,Aggregates are also used in agriculture, manufacturing, and other industries. An indispensable ingredient . Aggregates are an indispensable ingredient in ready-mix concrete, asphalt, and mortar. Accounting for approximately 60% to 75% of ready-mix concrete’s volume, aggregates strongly influence concrete’s freshly mixed and hardened properties.
