The famous Massachusetts Institute of Technology, Boston, USA, is supporting my re-agglomerated stone (concrete) pyramid theory. At MIT, Professor Hobbs and two colleagues and students are experimenting the construction of a small scale pyramid using my theory.

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

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 !!…

It is with sorrow that I learned that my friend Georges Grimal died at the age of 98 years. The majority of our scientific colleagues, engineers and students, know at least one of his works of Art created with geopolymer. It is displayed on this site at the page Potential utilizations in Art and Decoration

I met with Georges Grimal in 1981. Major General of the French Air Force, he had always been interested by new developments related to aeronautic, but at the same time he cultivated his gifts as a painter and sculptor. We had just manufactured prototypes in …

During my stay in Perth, Australia, on the last evening of our Geopolymer Workshop (Sept. 28 -29, 2005) organized by Prof. Vijay Rangan and Curtin University of Technology, I was interviewed by the Australian Talk Radio Network, radio talkshow anchor Graham Mabury . It was an interesting talk conducted by Graham Mabury who had studied the subject and prepared his interview with care. His questions were smart and pertinent.
