Pyramids — Deep Misleading analysis on the “Lauer Sample”.

By

On 21 May 2020

In Archaeology, News

Hundreds of thousands of people have read articles and seen videos on the internet dealing with the pyramids of Egypt having been constructed from geopolymer concrete. The arguments of the opponents are always based on the same papers written by American geologists, published 15 to 30 years ago. The most cited study shown in the videos at YouTube is the analysis carried on the “Lauer Sample” by the American petrologist D. Jana, published in 2007. It is time to put an end to this pseudo-science.

What is the Lauer sample?

The controversy concerns the analysis performed on a sample of …

Ultimate Proofs Tiwanaku / Pumapunku Megaliths are Artificial Geopolymers

By

On 7 Aug 2018

In Archaeology

At the 10th Geopolymer Camp in 2018, Prof. Joseph Davidovits presented during his annual keynote a brief summary of his last studies on the Tiwanaku (Tiahuanaco) / Pumapunku Megaliths. In November 2017, an international team (a geologist from Universidad San Pablo at Arequipa, Peru and a member of the Geopolymer Institute) went on the site to carry on a survey on these stones. After different analysis on thin sections and under an electronic microscope, Joseph Davidovits claims that his team has found “organic matter in volcanic rock“, which is, by nature, impossible. This points to man-made stone and …

Toowoomba, Brisbane West Wellcamp airport, Australia #Wellcamp747

Australia, October 2015.Brisbane West Wellcamp Airport (BWWA), Toowoomba, Queensland, is Australia’s first greenfield public airport to be built in 48 years. BWWA became fully operational with commercial flights operated by Qantas Link in November 2014.

30 years after my invention of Geopolymer cement in USA, at Lone Star Industries (Pyrament cement), this project marks a very significant milestone in engineering – the world’s largest geopolymer concrete project, so far. BWWA was built with approximately 40,000 m3 (100,000 tonnes) of geopolymer concrete making it the largest application of this new class of concrete in the world. The geopolymer concrete developed …

Wrong statement on Pyramids of Bosnia

By

On 22 Nov 2013

In Archaeology, News

I wrote in my main article dedicated to the Bosnian Pyramids an update stating that: “According to our information, we believe that the sample of concrete that I have examined under the electron microscope comes from a type of cistern or water tank (the drilling report is mentioning a concrete “ceiling” and an empty space of 4 meters depth followed by a “concrete” floor, see the pdf below). The geopolymer concrete analyzed is a kind of Roman concrete, which in no way corresponds to the materials that constitute the casing of the pyramids and look like pudding stone. Consequently, …

Paleomagnetism study supports Pyramid man-made stone

By

On 1 Feb 2013

In Archaeology

A recent scientific study published in the renown “Europhysics News“, The Magazine of the European Physical Society, (2012), Vol. 43, number 6, described how paleomagnetism study on several pyramid stones demonstrates the validity of Davidovits’ theory on the artificial nature of Egyptian pyramid stones.
Two scientists, Dr. Igor Túnyi from Geophysical Institute SAS – Bratislava (Slovak Republic) and Ibrahim A. El-hemaly from National Research Institute of Astronomy and Geophysics – Cairo, Egypt, made the following assumption (quote from their scientific paper):

Our paleomagnetic investigation of the two great Egyptian pyramids, Kufu and Khafre, is based on the assumption …

NOVA mini-pyramid: fiasco and swindle

By

On 19 Dec 2012

In Archaeology, News

In recent weeks, several internet forums discuss my involvement in a documentary made in 1991 by the American channel PBS, famous for it popular science program “NOVA” and entitled This Old Pyramid. The objective of NOVA was the illustration of different techniques proposed by experts in the construction of the pyramids of Egypt. NOVA had decided to build at Giza, a mini-pyramid, according to the “old techniques”. I related my experience in several of my books: in French (Ils ont bâti les pyramides, 2002; La nouvelle histoire des pyramides, 2004 and 2006) and in English more recently …

Geopolymer Revolution on the Move

By

On 9 Nov 2011

I am happy to see how Geopolymer science, which I founded 33 years ago, is generating applications and innovations dedicated to the general public. BASF, the world Chemical Company is strongly promoting geopolymer technology. In an older post posted in the Geopolymer Institute on 24 March, 2011, we introduced the geopolymer grout PCI-GEOFUG (go to BASF). Meanwhile, the company presents it at various international fairs and expositions, starting from Germany over UK, and presently in Paris, at BATIMAT (8 Nov., 2011). It is interesting to follow the arguments outlined in the company technical brochures dedicated to this geopolymer grout …

Revenge for ridiculed scientists: 2011 Nobel Prize in Chemistry

In News, Science

The revenge of the ridiculed scientists.
In September 2006, my article Publish or Perish: the disease of scientific research highlighted how the 2005 Nobel Prize winners in Medicine had been forbidden for years to publish the results of their research, simply because they contradicted what was taught in the faculties world-wide, and accepted by the majority of the scientific community at that time. The recent 2011 Nobel Prize in Chemistry, Daniel Schechtman, experienced a situation even more vexing. When in 1982, thirty years ago, he made his discovery of quasicrystals, the research institution that hosted him fired him because he …

Error or forgery on the Stele of Merneptah, known as Israel Stele

By

On 29 Jul 2010

In Archaeology, Books, News

The objectives of this article are twofold. First of all, it presents one information omitted in Chapter 11 of my last book in French language De cette fresque naquit la Bible (The Lost Fresco and the Bible ). Then, it denounces an error, or more probably the forgery of an archaeological document of the greatest importance.

Buy the new e-book on this issue at The Secrets of the Merneptah Israel Stele

The stele of Merneptah contains the oldest mention of Israel in an extra-biblical document. Flinders Petrie discovered it in 1896, at Thebes, Egypt, in Merneptah’s mortuary temple. Merneptah …
