It is a mystery that continues to baffle modern engineers. Why do 2,000-year-old Roman piers survive to this day, yet modern concrete seawalls embedded with steel crumble within decades?


Cool discovery. It wasn't mentioned in the article, but I've got to imagine there are potential gains for roadmaking in places like Michigan, where we use salt, as an ice melt for about a third of the year.
