100,000 tonnes Geopolymer Concrete: world premiere

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 by the company Wagners, known as Earth Friendly Concrete (EFC), was found to be well suited for this construction method due to its high flexural tensile strength, low shrinkage and workability characteristics. Heavy duty geopolymer concrete, 435 mm thick, used for the turning node, apron and taxiway aircraft pavements, welcomes a heavy 747 cargo for regular air traffic between Toowoomba-Wellcamp BWWA airport and Hong Kong..(See the video on my visit to the Toowoomba-Wellcamp-Airport).

Wrong statement on Pyramids of Bosnia

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, the information published on the Bosnian Pyramids websites are inaccurate. » Read the entire article at Pyramids in Bosnia.

Paleomagnetism study supports Pyramid man-made stone

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):

NOVA mini-pyramid: fiasco and swindle

NOVA mini-pyramid (© J. Davidovits, 1991)

NOVA mini-pyramid (© J. Davidovits, 1991)

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 (Why the Pharaohs built the Pyramids with Fake Stones, 2009). I shall make it available for the first time on the internet as a pdf file below which reproduces some pages and figures of the English edition of « Why the Pharaohs built the Pyramids with Fake Stones ». At the arrival of the television crew, including myself, the mini-pyramid was practically finished and had two of it sides convered with their casing stones, not dressed. The workers had used trucks, forklifts and steel tools for their work, the material being soft limestone quarried at Tura, on the other side of the Nile. But the use of construction equipment was not shown in the documentary « This Old Pyramid ». The casing stones are absent on the back of the mini-pyramid which was never completed, as shown in the figure above and Figure 3.14 in the pdf file, taken at the end of filming and before the big traditional festival End of construction.

Geopolymer Revolution on the Move

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 GEOFUG.The French text is enthusiastic. On one page (it is page 2) one sees 3 women raising both arms above their head with placards that read, translated from French:

Daniel Shechtman Nobel Prize Award Ceremony 2011

Revenge for ridiculed scientists: 2011 Nobel Prize in Chemistry

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 « threw discredit on the University with his false science ». Why? Because he had the misfortune to make his discovery alone, without the help of other colleagues. Indeed, for the scientific authorities and institutions it is fashionable to proclaim that research is above all a team work. So that any individual discovery is suspect, subject to ridicule, worse, suspected of manipulation of results and scientific fraud.
The press release from Reuters News Agency dated of October 6, 2011 was entitled: Ridiculed crystal work wins Nobel.
I have often quoted in my books the philosopher Schopenhauer (1788-1860): the establishment of the truth passes through three stages: during the first it is ridiculed, in the second it is resisted, in the third it is considered as self evident. Daniel Schechtman has crossed the 3 steps. He was the subject of fierce resistance from one of the greatest scientists of the 20th century, Linius Pauling, Nobel Laureate in Chemistry and Peace Nobel Laureate. In 1985, he wrote: Daniel Schechtman tells non-sence. There are no quasi-crystals, there are only quasi-scientists!
Those who follow my research on geopolymer science know that I already went through the first two steps. Five to six years ago, we entered the consolidation phase, the third step. To see this, just look at the evolution of the number of scientific publications published each year on geopolymer science and applications.

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

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.

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 was the son of Ramses II. The stele describes the military campaign undertaken in 1207 B.C. against the Libyans, and, eventually a campaign to Canaan by which a group of people named Israel would have been destroyed. One reads in lines 26 to 28 of this stele, according to the official translation: The princes are prostrate, they say: let us be in peace! Nobody any more raises the head among the Nine Arcs. Tehenu is destroyed; Khati (Hittites) are in peace; Canaan is captive like its demons, Ashkelon is conquered; Gezer is captured; Yanoam became non-existent; Israel is devastated, it does not have more seed; Kharu became the widow of Egypt. All these countries are pacified. All those, which were in revolt were subdued by the king of Egypt of North and the South…

The Lost Fresco and the Bible (my new book in French)

I am presenting my 5th book on the Egyptian civilization, here in connection with the Bible, published by Éditions Jean-Cyrille Godefroy, Paris, ISBN 978-2-86553-216-2

Released on: 29 september 2009

In 1935 in Karnak, in Egypt, two French Egyptologists discover a fresco in the ruins of the memorial temple of Amenophis (Amenhotep) Son of Hapu, the most eminent scribe and scientist of ancient Egypt, Great chancellor of the Pharaon Amenhotep III, father of the monotheist Pharaon Akhenaton. Recently, 75 years later, I noted that the text of this fresco was reproduced word for word in the Bible, Genesis 41, when Pharaon installs the biblical Patriarch Joseph to rule over all Egypt. Royal scribe Amenophis Son of Hapu and the Patriarch Joseph are thus the same person. Moreover, the fresco contains a surprising detail which underlines its authenticity. Indeed, in Genesis 41, Pharaon names Joseph: çaphenat-paneah (sapnath-panéakh), a name which does not mean anything in Hebrew. Indeed, I discovered that çaphenat-paneah is the Egyptian name Amenophis Fils of Hapou, written reversely, from left to right, the hebrew language being written from right to left. The surprising detail in the fresco is that, precisely, the Egyptian name Amenophis is also written in hieroglyph reversely, from left to right, instead of from right to left like the rest of the text. There is thus absolute agreement between the fresco text and the Bible.
