Manufactured sand (M-Sand) is an additional of river sand for concrete structures. The crushed sand is of cubical form with grounded boundaries, washed and classified as a building material. Alternative aim for use of M-Sand is its accessibility and transport cost. Manufactured sand is created as rigid granite stone by crushing.
