20 years after the best seller book: The Pyramids: an enigma solved,after 20 years of new researches, and new discoveries,you will understand why the theory is more alive than ever, why more and more scientists agree, simply because it is the truth.
In this book, Professor Joseph Davidovits explains the intriguing theory that [...]

The famous Massachusetts Institute of Technology, Boston, USA, is supporting Prof. Davidovits’ 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 the method recommended by Davidovits.

The scientific magazine NATURE, vol. 444, 793 (14 december 2006) writes in his News about the recent analysis on pyramid stones:
Materials Science: Concrete evidence
J. Am. Ceram. Soc. 89, 3788–3796 (2006)
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 [...]

On November 30, the Journal of the American Ceramic Society has released a very important scientific research carried out on the pyramid stones, which confirms the theory developed by Professor Joseph Davidovits on agglomerated (artificial) limestone concrete (ancient geopolymer).

The pyramids stones are man-made (synthetic, artificial)
Cast in molds

The Pyramids at Giza have more than 5 million blocks of limestone, until now believed to be CARVED stones, new evidences shows they were CAST with agglomerated limestone concrete.
The website reveals how Ancient Egyptians built the pyramids using man-made stones, which look exactly like natural [...]

The scientific proofs

The “Lauer” sample under the optical microscope.
This photo shows a sample of the casing from the ascending passage of Kheops great pyramid, given by the French egyptologist Jean-Philippe Lauer in 1982 to J. Davidovits. Now, the cross section is characterised by the presence of organic fibers and air bubbles that do [...]

Why do geologists see nothing?
This is due to the geological glue, which, though artificial, is seen by the geologists either as an impurity, and therefore useless to study, or as a natural binder. At best, the analysis tools and the working methods of geologists consider the glue as a perfectly natural “micritic binder”. A geologist [...]

Summary of the Conference
by Joseph Davidovits
Vth International Congress of Egyptology, Cairo, Egypt,
Oct. 29-Nov.3, 1988.

Egyptologists have long claimed that no records exist which describe how the Pyramids were built. A stone stele is engraved on a rock at the island Sehel, near Elephantine, Egypt, north of Aswan. It was discovered in 1889 by C.E. [...]
