They found "traces of a rapid chemical reaction which did not allow natural crystalisation . . . The reaction would be inexplicable if the stones were quarried, but perfectly comprehensible if one accepts that they were cast like concrete."
The pair believe that the concrete method was used only for the stones on the higher levels of the Pyramids. There are some 2.5 million stone blocks on the Cheops Pyramid. The 10-tonne granite blocks at their heart were also natural, they say. The professors agree with the "Davidovits theory" that soft limestone was quarried on the damp south side of the Giza Plateau. This was then dissolved in large, Nile-fed pools until it became a watery slurry.
Lime from fireplace ash and salt were mixed in with it. The water evaporated, leaving a moist, clay-like mixture. This wet "concrete" would have been carried to the site and packed into wooden moulds where it would set hard in a few days. Mr Davidovits and his team at the Geopolymer Institute at Saint-Quentin tested the method recently, producing a large block of concrete limestone in ten days.

Were the Pyramids Made with Concrete?
Some scientists are saying that the Ancient Egyptians made the pyramids with concrete. Here's a quote:

If the bricks they made were large enough for pyramids, the Egyptians would have needed a lot of ash.
This information might give provide additional weight for the burden that Pharoah was placing on the children of Israel when he said,
"You are no longer to give the people straw to make brick as previously; let them go and gather straw for themselves. But the quota of bricks which there were making previously, you shall impose on them; you are not to reduce any of it. Because they are lazy, therefore they cry out, 'Let us go and sacrifice to our God.'" Exodus 5:7-8
