Hi all,
This video presents an interesting view of the use of sand in manufacturing (of concrete), and why the quality and age of the sand matters. As concrete is central to city construction and is the most used (man made) material around the world, it's critical to modern society.

I'd be interested how crushed glass would work as a natural sand substitute. Considering that glass is difficult to conventionally recycle, perhaps it can be the "core" of a new construction blend. My town had to change glass from a recycled material to trash, as it had no demand from glass makers any more, so concrete use could be a win-win.
