M-Sand

  • In three months, the TN State government will put in place an M-sand policy that aims to promote the use of M-sand as an alternative building material.
  • It is aimed to eliminate the pervasion of sub-standard products in the market through regulation of trade.

Manufactured sand (M-Sand)

  • M-sand is a substitute for river sand for concrete construction.
  • Manufactured sand is produced from hard granite stone by crushing.
  • The crushed sand is of cubical shape with grounded edges, washed and graded as a construction material.
  • The size of manufactured sand (M-Sand) is less than 4.75mm.

Why use M-sand?

  • Manufactured sand is an alternative to river sand.
  • Due to the fast-growing construction industry, the demand for sand has increased tremendously, causing a deficiency of suitable river sand in most parts of the world.
  • Due to the depletion of good quality river sand for the use of construction, the use of manufactured sand has increased.
  • Another reason for use of M-Sand is its availability and transportation cost.
  • Since manufactured sand can be crushed from hard granite rocks, it can be readily available at the nearby place, reducing the cost of transportation from far-off river sand beds.
  • Thus, the cost of construction can be controlled by the use of manufactured sand as an alternative material for construction.
  • The other advantage of using M-Sand is, that it can be dust free, and the sizes of m-sand can be controlled easily so that it meets the required grading for the given construction.
  • Usage of M-sand prevents dredging of river beds to get river sand which may lead to environmental disasters like groundwater depletion, water scarcity.
