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. [...]

Concrete experts talk today about how to make concrete durable. Many ancient Roman concrete buildings are still in use after more than 2000 years. For these modern concrete [...]

Fabrication of stone objects, by geopolymeric synthesis, in the pre-incan Huanka civilization (Peru)
Joseph DAVIDOVITS and Francisco ALIAGA
Abstract of a paper presented at the 21st International Symposium for Archaeometry, Brookhaven National Laboratory, New York, USA, 1981 (page 21).
It is now agreed, that the TIHUANACO civilisation is modeled on the pre-incan HUANKA civilisation revealed by an extraordinary [...]

Synthetic stone in Ancient Egypt and Mesopotamia
manufacture of synthetic lava and synthetic basalt and decipherment of the C-14 Irtysen Stele (2000 B.C.)
The C-14 Irtysen Stele dating 2.000 BC (Louvre Museum, Paris) states that sculptor Irtysen [...]

Joseph Davidovits has found revolutionary ways of producing cements with plants saps, which could explain some of the mysteries associated with Pre-Columbian architectures. Preliminary results had been presented at two International Archaeometry Symposia. See in the library the paper #C Making Cements with Plant Extracts disclosing information dating back to 1981 and 1982.
In 1979, at [...]

I’m a sixth form student studying chemistry. I am interested in doing a project at college similar to the one you have done on recreating the stone used in the pyramids and building a small replica to show the method that might have been used.
I’ve looked over the information on this site and others but [...]

I recently read your book regarding the construction of the pyramids and was impressed with the overall coherence of the theory. Hopefully, in the future, popular opinion will swing in your favor so that you might be allowed to take pyramid samples of your own. This theory is strangely prone to ridicule, yet resistant to [...]

A letter from David Martin about Davidovits’ pyramid theory that illustrates how narrow minded people behaved when facing such problem.
In your book,”The Pyramids”, you discuss possible casting methods for the casing stones of the Great Pyramid and Red Pyramid. You mention that there were inscriptions on the bottoms of these blocks, indicating they were cast [...]

Long-Term Stability of Geopolymeric Materials

The task LONGTERM in the GEOCISTEM project dealt with the better understanding of long-term durability. It is difficult to predict extended durability on the basis of operating experience, laboratory experimentation and prototype testing. Two thousand years are generally accepted as a sufficient amount of time to permit decay of [...]
