TIL that even after 78 years, the cement in the Hoover Dam is still curing. As far as I know, concrete curing is a reaction that could potentially be occurring for thousands of years. The more it cures, the slower it cures, meaning it might never finish curing, it would just approach an extremely slow rate.
What material is the Hoover Dam built out of?
