Question

mention one advantage and disadvantage of dust in air​

Answer 1

Answer:

Stone dust is not used in good concrete especially in ‘ Controlled Concrete ‘. Use of Stone dust is going to drastically reduce the workability of concrete. This is so because the stone dust particles are not rounded like natural sand particles but are more likely to be needle shaped. This causes difficulty in producing a workable mix. Stone dust causes the same problem that crushed sand ( used in lieu of natural sand ) causes. I do not know of any advantages in using crushed sand.
