I thought the concrete theory had been disproved. I do believe the Sphinx is older though. I think the Egyptians modified it but didn't build it.
Posting just popped up by Redewenur.
Davidovits, is the guy who first proposed the Pyramid was built of Concrete! Wikipeadia (got it wrong) stating that ALL the pyramid was cast!!
I originaly understood that only the smooth white casing stones were cast.
The URL and others state that they must have been cast using a limestone aggregate. So where did they get the crushing machinery from?
Five tons mixed and cast, in situ, Sun dried blocks next each other? That would have meant blocks would have been joined to the lower blocks, that the concrete was sitting on. Any slurry mixtures that dripped down would have been found today.
It means the 5 ton cast blocks would have beem more dense towards their base.
And what about the sloping tunnels within the Pyramid? How to cast those, in situ, with no drips? Pull the other leg.

And yes, scpg02 the Sphink is accepted by the Egyptian authorities as being considerably older. It shows rain water channels etched into its lower plinth.
While its face had been recarved later, to show the Pharoeh (Kufu?) at that time.
The sphinx is sitting on a limestone plateau. Using Electronic technology some years ago it was shown that there is an underground chamber sitting beneath its front paws
