Sigh. Yet another LAOA comprehension fail. I was responding to 1234's contention that structures built with cement prior to the 20th century are hopelessly compromised by inferior quality, by pointing out that the world's largest unreinforced concrete dome is somehow still standing after nearly 2,000 years.

Oh, and portland cement was developed in the early part of the 19th century.
