Suitability of Crushed Manufactured Sand for Replacement
The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60% to 75% concrete volume (70% to 85% by mass) and strongly influence the concrete’s fresh and hardened properties. Now a day’s sand is becoming a very scarce material. Natural sand deposits are being depleted and causing serious threats to

Using of Robo Sand or M Sand instead of natural sand
Advantages of M sand are : Less dependency on natural sand resources. Crushed aggregates produce lot of fines and instead of wasting , it could be mixed with natural sand and used if it passes proper gradation tests. Disadvantageous are : M sand by itself may not pass physical tests as required by codes.
