Properties of concrete are influenced by many factors mainly due to mix proportion of cement, sand, aggregates and water.
Manufactured Sand vs. Natural Sand - Concrete, …
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.
Manufactured sand production - liming
The price of manufactured sand can also be lower compared with natural sand, which decreases the production cost of the concrete even further. If we consider the fact that natural sand sources are getting scarcer, especially close to urban areas, transportation costs can be considerable if the sand has to be transported with trucks from tens of kilometers away.
