Has the sand issue been resolved? It'd been reported that we're running out of sand suitable for concrete. Yes, I know, "Sand? Are you crazy? The world is full of sand!". But river-polished coarse sand is no good for concrete. It has to be of a particular size and roughness to be any use. And the easy sources had run out. Sure, you could find a process to 'make sand'. But it by definition is more expensive than 'drive a truck to where the right kind is lying on the ground and load it up'. So the price of concrete went through the roof. The 'age of concrete' may be over. So this issue may be moot.
