They're using crushed rocks and mining material leftovers to create artificial sand, thereby reducing their dependence on natural sand by around 80% so far. Saved y'all a click.

I'm somewhat relieved they weren't grinding up plastic waste to mix into their sand.

Tofu Dreg, they also love using beach sand as an aggregate. Problem is all the salt, then the rebar rusts, swells and destroys the concrete.

/used to pour concrete.

Crushing gravel and other mining waste into sand isn't quite "artificial" sand...

Like how there's no such thing as an artificial diamond, just a man made one.

The sand is sand, it's just mand made.

Would crushed beton also work? I mean, if the piece size and form is right.

I live at in Central Florida, and there is a sand mine right down the road from me. The sand is so predominant here that there is literally a natural sand dune near there, nowhere near a shoreline. The local road divides it. We literally live on a beach 60 miles from shore.

Lemme guess. Impacts on concrete availability and construction supply chains
