French Chemistry Professor says he knows how the pyramids were built
From Professor Joseph Davidovits’ website:
-
“Professor Joseph Davidovits explains the intriguing theory that made him famous. He shows how the Pyramids were built by using re-agglomerated stone (a natural limestone treated like a concrete), and not with huge carved blocks, hauled on fragile ramps.”
Davidovits is author of many books, including Why the Pharaohs built the Pyramids with fake stones.
