Only the outside stones of pyramids were quarried

[srlip]

the rest of them were cast in place, using a sort of concrete that we no longer know how to make. This was proven decades ago, with examination of the block's material. Still a lot of work, but doable in one king's lifetime (which HAD to be the case). Wooden forms were made, hods of semi-liquid material were carried up the ramps and dumped into the forms. Presto, the very close together cracks noted in the block's placement.

I agree with this theory, and find it odd that so many focus on the least probable and far more difficult idea that all the under stones were carried by forded labor into place.

Forced labor really doesn't work all that well except for the simplest tasks and is often bungled even then.

Never heard of this theory before, but it makes sense.

THAT is pretty damn interesting. I've heard of different types of concrete that were forgotten by history such as the kind used by the Romans. But I've never heard of this before. Pretty cool.

This would be pretty easy to verify with common methods in petrography. Got any links?

Davidovits' hypothesis recently gained support from Michel Barsoum, a materials science researcher.[41] Michel Barsoum and his colleagues at Drexel University published their findings supporting Davidovits' hypothesis in the Journal of the American Ceramic Society in 2006. Utilizing scanning electron microscopy, they discovered mineral compounds and air bubbles in samples of the limestone pyramid blocks that do not occur in natural limestone.[42]

Similar to when you consider that a lot of the arch-bridges that the Roman's hewed out of stone are still in use today in Europe. Today. There are a number of such bridges still up between Köln and Aachen. Just amazing. I've walked over two of them. Briddges that are more than 2,000 years old.

Back in the day of Muscle Powered machines, you built things to last for ever because it was so darned hard to rebuild anything.

"Forced labor" is a very obsolete theory concerning pyramid building.
