minus-squareFranfran2424@lemmygrad.mllinkfedilinkarrow-up0·1 month agoSand is a limited resource. Not every sand works. Generally, it has to be river sand, because sea sand has salt and must be washed, and open air sand is pulished by wind, making it worse for building.
minus-squaredestroyamerica@lemmygrad.mllinkfedilinkarrow-up0·1 month agoah thank you for the info! seems like something i should have learned in school, although I learned very little about protecting the environment in school tbh so it’s not that surprising

minus-squareREEEEvolution@lemmygrad.mllinkfedilinkarrow-up0·1 month agoRiver sand is rougher, sea sand or desert sand is either too rough or almost polished round.
minus-squareFranfran2424@lemmygrad.mllinkfedilinkarrow-up0·1 month agoIt still works, it generally tends to crack more easily or damage steel bars due to salt.

minus-squareFranfran2424@lemmygrad.mllinkfedilinkarrow-up0·1 month agoYeah, that works. Then again, China is kind of demonstrating that crushing rocks into sand also works. So whatever pollutes less, I guess.
