In this video Er. Chetan Sharma, Corporate Trainer of Civil Guruji explaining about Which is best for House construction? | M Sand Vs River Sand | Manufactured Sand.
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 produced by crushing of quarry and rocks stones to desired sizes.

To derive the required sizes, these hard rock deposits are crushed, and this material is segregated in different fractions to suit different construction sites.
The chemical characteristics and strength of M-Sand(Manufactured Sand) are similar to river sand.
M-Sand(Manufactured Sand) as a silt content of around 0.2 percent and water absorption of 1.6 percent, as compared to 0.45 percent and 1.15 percent respectively in river sand
This sand alternative of river sand/natural sand.
M-sand(Manufactured Sand) cheaper sand as per river sand.
M-Sand Bonding Strength.
M-Sand is manufactured in a three-stage process:

Crushing:
Quarry and Rocks stones are crushed at jaw crushers, cone crushers, and vertical shaft impact crushers, respectively leading into the formation of angular and cubical fine aggregate particles.
Screening:
Screening ensures this material is properly graded that’s similar to river sand.
Washing:
Washing removes all the micro-fine particles. Also, fine aggregates for concrete and plaster sand are also formed.
Advantages of M-sand
The major advantage of manufactured sand is that it is highly cohesive and compressive in strength.
It has lesser impurities, which help in producing better quality concrete.
Moreover, the controlled gradation of Zone-II is possible, suitable for concrete.
In some case studies, it was found that concrete produced by using manufactured sand obtained 6-9 %(percent) higher compressive strength and 12-15 %(percent) higher flexural strength compared to river sand of the same grade.
