Pyramid: Cement and Concrete expert agrees!
My name is Prof. Mario Collepardi and I am a professor of “Materials Science and Technology” at the Politecnico of Milan, Italy. Yesterday I have seen your interview by Mr. Giacobbo at the “Stargate” program on “La 7″ Italian TV channel. I am very interested to your theory about the building technique used by Egyptians [...]
H2O, SiO2 and Al2O3 ratios
There is a clear relationship between water ratio and mechanical properties. The water is our carrier. Polycondensation happens between compounds that are soluble in water. It is the water content which determines the density of the matrix. After polycondensation, the excess of water which is not tied to the structure in the form of -OH [...]
Heavy metals immobilisation
Heavy metals immobilization follows two steps: First: dissolution, solubilization of the heavy metal, due to high pH (no precipitation as hydroxides); Second: charge balancing role like any cations (Na or K). Immobilization is not encapsulation, but regular geopolymerization. These steps are disclosed in French in the published International patent application WO 89/02766, titled “Method for [...]
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 [...]
Difference between geopolymer and amorphous zeolite
What is the mechanistic implications of the higher concentration of precursors in the case of geopolymer formation? In other words how does a higher precursor concentration affect the normal mechanism of zeolite formation (nucleation and crystal growth) in order to prevent crystal growth and create a geopolymer and not just an amorphous zeolite? My first [...]
Fundamentals on geopolymerization
I have been following your work now for a couple of years and are mainly concerned with the toxic waste field and the potential application of Geopolymeric binders towards a toxic waste solution. I will also be writing up a Ph.D on this subject within the next year. As I did not have a lot [...]
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 [...]
