M-sand is crushed aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand. Natural river sand had been the principal constituent of all construction activities over centuries. But unscrupulous and ruthless excavation of river beds led to the fast depletion of this once abundant natural resource which actually took millions of years to attain its present form.
Excessive in-stream sand and gravel mining caused the dipping of water levels, degradation of rivers and river bank erosion. In many regions of the world, the extraction of sand and gravel is heavily taxed or banned completely to preserve remaining deposits.
Sand researchers world over were in continuous research to find an alternative for river sand, who zeroed in on manufactured sand or popularly known as M-sand.
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, it can be dust free, the sizes of m-sand can be controlled easily so that it meets the required grading for the given construction.
The common requirements for the manufacture sand are:

The common requirements for the manufacture sand are:
*All the sand particles should have higher crushing strength.
*The surface texture of the particles should be smooth.
*The edges of the particles should be grounded.
*The ratio of fines below 600 microns in sand should not be less than 30%.
*There should not be any organic impurities
*Silt in sand should not be more than 2%, for crushed sand.
*In manufactured sand the permissible limit of fines below 75 microns shall not exceed 15%.
*The surface texture of the particles should be smooth.
*The edges of the particles should be grounded.
