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:
All the manufactured sand particles should have enough or more crushing strength.
The surface texture of all manufactured sand particles should be smooth and it should not be rough.
All the ages of particles should be well-grounded.
When you talk about the ratio than the ratio of fines below than 600 Micron inside should not be less than 30%
Manufacturers and should not contain in organic impurities in it
It is not possible that any impurity is not present in the manufactured sand but if it is present then it should be within its permissible limit.
When we talk about silt percentage in the manufactured sand then it should not you more than 2%
The permissible limit of finance below 75 Micron should not be more and 15%. (The sizes of particles which are less than 75 Micron then it includes mainly clay and silt.)
