Pyramids built of limestone, not concrete blocks

Egypt's Pyramids in Giza are built of limestone, not concrete blocks as a French chemist claimed recently, said Zahi Hawwas, Chairman of the Supreme Council of Antiquities.

In statements on Thursday, Hawwas said the quarry where the stones were brought from had been spotted 150 kilometers south of Cheops Pyramid.

"The French Chemist, Joseph David, has never visited Egypt neither has he ever seen the Pyramids," said Hawwas.

"His idea is an old one which he published in a book several years ago and did not distribute more than 1.000 copies," added Hawwas.

Hawwas believes that the French chemist reached this conclusion because the samples he worked on came from wrong renovation conducted in the past century on the exterior of the great pyramid's stones.

This method is now absolute, added Hawwas.
