Over a long time. Upkeep requires investment. There's a lot of American infrastructure seriously in need now, and that's over decades, not centuries.

The romans used volcanic ash in their concrete. Huge difference in how long their structures survive even harsh conditions vs modern concrete. https://www.historicmysteries.com/roman-concrete/

Has anyone tried to recreate this in modern buildings? I'm actually semi-interested in building a house

Roman concrete has longer drying time and lower strength but it is MUCH more durable. Roman concrete was still gaining strength for DECADEs after construction was completed.
