(urth) Concrete

[David Stockhoff]

I agree that concrete is a tough technology to lose. The Romans had it. 
If anything, modern improvements have only produced weaker, 
shorter-lived but quicker-setting concrete.

I also agree that the spaceport would have included a flat concrete pad 
at one time. Whether it still exists in Severian's time is another 
question. But surely there wouldn't be any stones UNDER the rocket ships 
that form the towers of the Citadel.

IMHO.

Is there some reason that I've not yet thought of that would prevent concrete casting from being a viable technology on Urth in Ymar's or Severian's time  It strikes me that concrete casting is a method that humanity would not lose, and I can't think of any reason why it wouldn't be used on Urth.
