You have hit the nail on the head there Shambles - Concrete... is so deeply a part of the modern architectural lexicon that some people have risen up against it, and call it a flexi- con. But these anticementites, I believe they have a problem with the boundaries of their own egos - and so they have focussed unecessarily on cement as a symbol for their own unbound, scattered narcissist fantasies.

personally I think everyone should indulge in a little concrete - the world would be a better place.
