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.
