Manufactured Sand vs. Natural Sand
Manufactured sands tend to be used in mixtures in areas where natural sand is not available or not cost effective to be hauled to the needed location. MFA tends to be more angular and flaky due to the crushing process. Highly angular particles tend to increase the paste content of concrete because additional lubrication is required for particles with sharp corners.

An Investigation into the Use of Manufactured Sand as a 100%
The results show that the manufactured sand concrete made in this study generally requires a higher water/cement (w/c) ratio for workability equal to that of natural sand concrete due to the higher angularity of the manufactured sand particles. Water reducing admixtures can be used to compensate for this if the manufactured sand does not contain clay particles. At the same w/c ratio, the

Could Desert Sand be Used to Make Concrete?
In 2015, Mental Floss discussed the reason desert sand could not be used to make the concrete. They explained that, because it is wind-swept, the sand is too fine and won''t achieve the texture of water-swept sand in manufacturing. Given the amount of water-swept sand left and how mining is beginning to go beyond riverbeds and onto beaches, new
