The main flaw that strikes me in that whole highly ambitious argument is in
order to make any form of concrete you need powdered rock.  Admittedly rock
can be powdered by crushing and grinding, so not impossible with primitive
means, just bang the rocks together. But you'd need an awful lot of concrete
to build the great pyramid.

The other aspect is where is the information that shows how this rock was
hardened and set. If the mixture didn't have the right properties it would
not harden properly. The other thing is the author talks about Diorite pots,
this substance is said to be as hard as quartz. Obviously it would be very
difficult to grind such a material into a powder, and even if you could make
a kind of diorite concrete. I imagine one would need to fire the pots in a
kiln so that the particles could re-fuse together to the same hardness. But
what about granite? How does one make granite concrete? Processes that
involve firing usually require the inside of the object be hollowed out
otherwise it will crack and fall apart, anyone who has ever done ceramics
knows this. The only other method that might work is some form of internal
heating process involving microwaves or ultrasound carefully controlled
using computers and technology very likely beyond even what we have today
and certainly not available to the Ancient Egyptians.

It's an interesting idea but apart from an attempt to debunk the idea that
the Egyptians had power tools the author provides no supporting evidence to
show geopolymerization actually works or is a viable explanation. She merely
uses long words with no evidence to support her argument.

In fact I'm pretty certain if one studied geopolymerization fully one would
discover the heat and pressure necessary to fuse some types of rock together
in that way would only be available to a highly technologically advanced
people. Actually similar theories have been postulated about those Crystal
skulls, but moulding and fusing quartz in that way is AFAIK beyond current
technology so if that is how it was done, it would suggest they were made by
a people with technology far beyond our understanding.
