i jeard that sahara sand is practically useless for that

or maybe that was just for concrete or something

It can't be used for concrete because it's too smooth due to erosion. Industrial sand is manufactured to have sharp edges so it holds better.

I heard beach sand is pretty good for concrete. Apparently there is something called sand mafias in (iirc) India which basically steals sand from beaches and sells it.

Beaches, rivers you name it. Flowing water makes the best kind of construction sand.

In bangladesh, the sand mafia have literally eaten through making rivers extra wide.
