If you look at it as a logistics problem this Theory makes a ton of sense.

It seems like Egypt has high quality limestone to make the lime component of concrete. And the area is obviously not in short supply of silica.

I wholeheartedly agree. The hypothesis has the advantage in being 100 percent compatible with all the other serious hypotheses that are out there, and a number of the ones that are hard to take seriously.

I found out about JD's book way back when from the late William Corliss (a kind and patient correspondent, for which I'm grateful) wrote about in his Science Frontiers newsletter and gift shop. The way he had his avocation figured out, I wonder what heights he might have hit in the internet era.

No it doesn't. Concrete requires a system of forms which means wood. It requires lots of water. First to mix it and then to cool down the concrete as it drys.

The Pyramids had what archaeology describes as a limestone covering but it's clear to see the structure is composed of large stone blocks.
