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).
It is recommended to use crushed sand. It is an economic and ecological alternative to natural sand. Crushed sand possesses properties similar to that of river and is a more sustainable construction material. Scientifically use of crushed sand will provide a long-term solution to construction industry to overcome shortage of river sand.
River Sand is usually obtained from River Beds and Banks. It is usually very fine in quality and has a white-grey color. River Sand is good for all construction activities like concrete production and plastering as it is well graded. As per the Indian Standard codes, sand used in preparation of concrete and in plastering should ideally confirm to IS-383 Zone-II.
