What a joke, when you see how all the bridges built in the 60s and 70s are crumbling apart.
- pharke 7y agoThat's actually solvable by using another product of high-heat processes, basaltic rebar. The main problem with concrete infrastructure is that water eventually infiltrates down to the rebar and wire mesh used to add tensile strength causing it to rust and expand which breaks apart the concrete. If you use something with equivalent tensile strength that doesn't rust then you get construction that lasts many, many decades longer.
