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. 

It would have been nice if Margaret Morris actually had some
technical background in the field of which she goes on about,
and simply had more than 'researcher' to her credit.
Her confrontational debate attitude, I think is more offputting
than of help to her.

At least Christopher Dunn has more than that, to his credit - he
is more creditable with his theories because it is within his
area of expertise and knowledge that he talks about.
