Researchers discovered that waste from your morning brew could revolutionize construction materials, making concrete dramatically stronger while solving a global disposal crisis.
While it’s nice to use a bit less sand, charring at 350°C doesn’t sound like negligible energy usage. Especially if done with fossils. Always good to have options, I guess?
Last I heard we are running out of sand to use in concrete so it might not be an environmental thing just a cost. Like they can’t just use any ol’ sand. Beach sand is too smooth or something so it has to be river sand I believe.
Other way around. Beach sand is new and this rough. A surprising amount of it is parrotfish poo, chewed up coral. River sand, and desert sand, is weathered and smooth.
I’ve seen a machine for pulverizing glass bottles into basically sand. Smooth desert sand > glass packaging, used for food, glass packaging > concrete aggregate?
