Making stone simpler guide?
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 [...]
Replicating egyptian stonework
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 [...]
Pyramids: opponents missing the big picture?
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 [...]
Archaeological Analogues (Roman Cements)
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 fission [...]
#10: From ancient concretes to Geopolymers
Arts et Métiers Magazine N°180, Sept. 1993: From ancient concretes to geopolymer “Des bétons antiques au géopolymère” ( in English, en Français ) This paper has been adapted from an article written for the general audience by two independent French journalists. It outlines the story of geopolymer and his inventor Prof. Joseph Davidovits . Click [...]
#F: Why Djoser’s blue Egyptian faience tiles are not blue?
IXth Egyptology Congress, Grenoble, 2004 Why Djoser’s blue Egyptian faience tiles are not blue? Manufacturing Djoser’s faience tiles at temperatures as low as 250°C? by Joseph Davidovits and Ralph Davidovits 30,000 blue faience tiles were found in Djoser’s funerary complex at Saqqarah (3. dynasty). It is generally assumed that the tiles underwent a self-glazing process [...]
#E: Searching for Carbunculus (“A la recherche du Carbunculus”)
A la recherche du Carbunculus (searching for Carbunculus) by Frédéric Davidovits, Université de Caen published in Revue Voces, Vol. 5, pp. 33-46 (1994), ( in French, en Français ) Abstract in English: Carbunculus, as described by Vitruvius (2, 4, 1; 2, 6, 6; 8, 1, 2), is a mineral used like a pouzzolana, which, when [...]
#D: The synthetic pozzolanic mortar by Vitruvius
Les mortiers de pouzzolanes artificielles chez Vitruve: évolution historique et archirtecturale DEA thesis by Frédéric Davidovits, université de Nanterre – Paris X, 1993 ( in French, en Français ) Contrairement à ce que l’on croit généralement, les sables employés dans les mortiers dits hydrauliques chez les romains sont de nature pouzzolaniques car d’origine volcanique. Des [...]
#C: Making Cements with Plant Extracts
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 [...]
