Sand of various types are running out around the world, and it can be quite the expensive challenge to get the right type for your particular project, many times involving trying to preserve land from water erosion.
Maybe industry is working to create artificial sand grades for current and future projects, I’m not sure…
River sand is the right amount of jaggedness to where it can pour and settle into the right density in cement to have the right strength in the finished concrete. Ocean/beach sand works, too, but needs to be rinsed with fresh water, and is usually pretty valuable where it is (for beach resorts and what not).
They’re testing for how to use different types of sand (desert sand, manufactured sand, recycled sand) and testing the pouring characteristics and resulting concrete strength, so that they can make reasonable decisions on when it’s worth using substitutes.

Thats pretty shocking to my untrained ass. I always assumed they did mass-produced sand, grinding up their own stones and stuff.

One would think, right?
I’m not remotely knowledgeable enough to say with any confidence, but:

EDIT : well, hate on me if you like, but I think this seems to clarify things.
