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.

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
