M Sand is nothing but artificial sand made from crushing of rock or granite for construction purposes in cement or concrete. M sand differs from natural river sand in its physical and mineralogical properties. Sand is one of the important ingredients at making concrete mortar & plaster, etc.. Earth scientists and organizations are now promoting the use of M-Sand(Manufactured Sand).

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.
construction requirements? Minimum Depth: The string of well casing pipe–not including the screen–must extend to at least the 25-foot depth or to at least 10 feet below the static water level, whichever is the greater depth. This is the same minimum casing depth as required for private drilled wells. (The static water

May 07, 2020· 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.
