What are the advantages and disadvantages of using Robo sand or M-sand instead of natural sand in concrete of footings, columns, and slab? What are the steps needed to be taken to mitigate disadvantages if one uses Robo Sand/ M Sand?

Hi, I thought you get your answer from the above comments. But as you mentioned in the question about his safety, yes the M sand safe for construction purposes up to some extent and after using some admixtures. Basically, rivers and is very costly. And the sands of the river selling on the base of weight. If M sand is available in the local area as it is the best choice to use. In Hyderabad, most of the power plants use a Robo sand or M sand and rock sand. Because the rivers are situated far away from the city location.

Manufactured sand is far more better than river sand.
Advantages of M-sand are:
The results of my project were:
Commenting on the results I would say
Hence, I conclude that M-sand concrete possesses higher compressive strength when compared with river sand concrete. The results pertained to that M-sand can be 100% replaced and possess greater characteristic strength. The present investigation shows that characteristics of concrete made of M-sand as fine aggregate are superior when compared to natural river sand as fine aggregate.

Manufactured sand:
There is no doubt that the manufactured sand is not a good replacement for the river sand.
We can definitely use to manufacture signed in the construction industry mainly for concrete production and mortar mix. Basically manufactured sand is nothing but a crushed of fine aggregate which is produced from the source material with suitable strength, durability, and shape characteristics.
The general crashing of hard stones with the help of jaw and cone crushers we can produce poor weak and flaking particles which are for the crushed in vertical shaft impact Crusher is a waiting process to eliminate impurities and silt content from it.
Now I am discussing basic requirement to be made for producing manufactured sand, have a look:
Thank you.

Supply of material not available all time and fluctuations in cost can hamper Project Cost. extraction of sand from river bed is environmental hazard and ban in many places. Contains no organic, harmful impurities, hence significant improvement in strength of concrete at same cement content.

The first advantage of M-Sand is that it is cheaper than river sand and is easily available. Check this link for all the details: Manufactured Sand (M-Sand) for Concrete -Properties and Advantages

it has a rougher texture than river sand
it has no over sized materials or silt
it provides higher concrete strength compared to river sand
it’s cheaper than river sand
it’s eco-friendly since m sand uses natural coarse aggregates to form

Advantages of M sand are :
Disadvantageous are :
I would rather overcome disadvantages of M sand by using controlled manufacturing process to meet code requirements pertaining to fine aggregates.
