What are the Materials for Replacement of Sand in Concrete
The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.

Manufactured Sand in Concrete | GCP Applied Technologies
More and more, GCP Applied Technologies'' scientists and technical experts have observed the use of manufactured sand over natural sand, as a fine aggregate in ready-mixed concrete. THE PRIMARY REASON: Environmental concerns have made what remains of available natural sand resources an economically unviable option for the concrete producer.

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

Manufactured Sand (M-Sand) in Construction
Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete. We are also using M-sand for current project.
