Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.

Sand may constitute between 30 and 40% of the main components of concrete – or even higher, depending on the mix design – but is has a great influence on the amount of cement required to achieve the concrete properties demanded. Here, cement will represent an average 50% of the cost of the total mix. High-quality manufactured sand will therefore not only offer benefits by improving

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.

Natural river sand is one of the main ingredients of the concrete but is becoming expensive for various reasons. Also, the concern for environment is making the sand quarrying more and more difficult. Thus, there is a need of a cost-effective alternative and that is available in the form of manufactured sand (M-sand). In this experimental study

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.
