(from businessweek.com source Bernhard Warner:)
“As anyone who’s ever visited Italy knows, the ancient Romans were master engineers. … One such structure that has fascinated geologists and engineers throughout the ages is the Roman harbor. Over the past decade, researchers from Italy and the U.S. have analyzed 11 harbors in the Mediterranean basin where, in many cases, 2,000-year-old (and sometimes older) headwaters constructed out of Roman concrete stand perfectly intact despite constant pounding by the sea.”
It has been known forever, there is a construction near Rome, that the nazis tried to blow up in WW2 with no success.
Since then, every single demolition company who has won a bid to demolish it, went out of business for non performance.
That explains eloquently how you make artifacts to last 2k years, ‘long life cycle’ is science, while ‘monetary efficiency’ is what it is, quackery.
Can you see the ‘architects’ of SPQR, Inc trying to sell the Roman Emperors a ‘service contract’ for their buildings ? LOL 😉
