    Difference Between M Sand Vs River Sand What is MSand

    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 amp plaster etc.. Earth scientists and organizations are now promoting the use of M-SandManufactured Sand.
