Manufactured Sand vs. Natural Sand
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.

Considering Manufactured Sand
The first step in the production of manufactured sand is crushing the rock to a gradation that when classified, by only removing the excess material passing the #100 and #200 sieve, will meet the C-33 Sand Specification on all the other sieves (#4, #8, #16, #30 and #50). Normal manufactured sand will result in sand with less then 80% passing ...
