Geopolymer Institute

By Joseph Davidovits
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.

For thousands of years sculpture has been invented to be seen in daylight. Today, artificial light opens the door to a new approach, all the more so since the advent of new materials, upsetting our concepts in many [...]

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 [...]
