Joseph Davidovits

The world press is commenting the study published by the French science magazine Science & Vie and the scientific paper released by the Journal of the American Ceramic Society , December 2006.

Here some links and excerpts from major English, American and German news papers

Materials Science: Concrete evidence

The scientific magazine NATURE, vol. 444, p. 793 (14 december 2006) writes in his News about the recent analysis on pyramid stones:

“Some of the massive blocks making up the great pyramids of Giza in Egypt (pictured) are not limestone, but a synthetic mix like concrete, argue materials scientists. The paper by Michel Barsoum of Drexel University in Philadelphia, Pennsylvania, and his colleagues is the latest entry in a decades-long argument. Most Egyptologists reject the idea, put forth in the mid-1980s by French chemist Joseph Davidovits, that the pyramids contain concrete. Barsoum’s team took a fresh look at 15 samples using scanning- and transmission-electron microscopes. The samples contain ratios of elements, such as calcium and magnesium, that do not exist in nearby limestone. The imaging also revealed regions of amorphous structure. Both observations suggest that other substances were added to make a concrete mix, say the authors.   Lire la suite... / Read more...

It is obvious that, with his statement published on December 1, 2006, in the New York Times , Dr. Hawass, General Secretary of the Egyptian Antiquity Organisation, thought that the renowned material scientists, professors M. Barsoum, G. Hug and G. Demortier, had analyzed modern Portland cement concrete instead of the re-agglomerated (reconstituted) limestone, as claimed by Professor J. Davidovits.

This is a pure affront to the scientific integrity of these well known scholars. Will Zahi Hawass apologyse for his mistake and present his regrets? The future will tell, and I hope he’ll do it !!   Lire la suite... / Read more...
