Sand for construction is a limited resource. Not every sand works to make concrete.
Generally, it has to be river sand, because sea sand has salt and must be washed, and open air sand is pulished by wind, making it worse for building.

It still works, it generally tends to crack more easily or damage steel bars due to salt.
