Ancient Concrete

How the Pyramids were built: Ancient Concrete. Chris Everard is an eccentric and interesting former music producer and engineer. In this documentary, he observes something familiar about the chambers in the Great Pyramid - namely the perfect leveling, traces of floating (like in plaster) and lock tight fitting. He concludes: much of the pyramid interior is set to cement similar to our modern 'liquid marble' tabletops.
