In recent weeks, several internet forums discuss my involvement in a documentary made in 1991 by the American channel PBS, famous for it popular science program « NOVA » and entitled This Old Pyramid. The objective of NOVA was the illustration of different techniques proposed by experts in the construction of the pyramids of Egypt. NOVA had [...]

Mon livre Geopolymer Chemistry and Applications en Chinois. My book Geopolymer Chemistry and Applications has been published in Chinese by a major publisher, National Defense Industry Press, ISBN 978-7-118-07421-5, 2012.

I am happy to see how Geopolymer science, which I founded 33 years ago, is generating applications and innovations dedicated to the general public. BASF, the world Chemical Company is strongly promoting geopolymer technology. In an older post posted in the Geopolymer Institute on 24 March, 2011, we introduced the geopolymer grout PCI-GEOFUG (go to [...]

The revenge of the ridiculed scientists. In September 2006, my article Publish or Perish: the disease of scientific research highlighted how the 2005 Nobel Prize winners in Medicine had been forbidden for years to publish the results of their research, simply because they contradicted what was taught in the faculties world-wide, and accepted by the [...]

A new scientific analysis demonstrates the artificial nature of Egyptian Pyramid stone. The article titled: « Were the casing stones of Senefru’s Bent Pyramid in Dahshour cast or carved? Multinuclear NMR evidence » was published in Materials Letters 65 (2011) 350–352, by an international team of scientists involving Kenneth J.D. MacKenzie (MacDiarmid Institute for Advanced Materials and [...]

The objectives of this article are twofold. First of all, it presents one information omitted in Chapter 11 of my last book The Lost Fresco and the Bible (De cette fresque naquit la Bible). Then, it denounces an error, or more probably the forgery of an archaeological document of the greatest importance. The stele of [...]

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. Go to the Boston Globe article of April 22 2008 titled A new angle on pyramids Scientists explore [...]

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, [...]

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 [...]

Walter Sullivan, science editor and writer at the New York Times, was the first English speaking journalist to write that the Egyptian pyramids may have been cast from plastic rock instead of being hewn. I have been attending the International Archaeometry Symposium, held at the Brookhaven National Laboratory, Long Island from May 18 to May [...]

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.
