Answer 1

Sort of but at the same time no. Where do you have the sandpits? Close to big cities where you need all that concrete, of course, these pits have bottoms and you run out. There are plenty of places farther away you can dig for sand, but it’s farther away and maybe the quarry is not next to shippable river so it’s more expensive to transport. So you have run out of cheap and convenient sand, but pay more and of course there is more sand.
