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.
