At the 17th Geopolymer Camp, Professor Joseph Davidovits delivers a special keynote to celebrate his 90th birthday. Instead of the usual technical R&D update, he shares the fascinating and personal story of how a tragic fire in the 1970s led him to invent Geopolymer science. He recounts his journey, the unexpected connections to archaeology, and the challenges he faced in establishing this revolutionary field. A must-watch for anyone interested in innovation and perseverance.

Summary: From a practical engineering perspective, you will learn which printing head and admixture work best, how computer simulation can accelerate development, which materials are best for printing a geopolymer slurry, and which selection criteria are most important. Finally, an LCA study will support the challenge of climate change. Dr. Abrar Gasmi thesis will be available for free download in the next months.

Join Dr. Abrar Gasmi as she details her PhD research on the multiscale optimization of 3D printed geopolymer ceramic, a key collaboration with Pyromeral Systems and the Geopolymer Institute. The goal: replace energy-intensive, waste-generating refractory molds—used for high-performance aerospace and motorsport components—with an eco-friendly, precise, 3D-printed alternative.

The journey focused on overcoming major challenges, including finding a printable formula and preventing layer collapse. Dr. Gasmi selected M88 metakaolin from temCon, feldpsar and Wollastonite from Xatico, with potassium silicate from Woellner, and optimized the rheology using additives like xanthan gum, also from Woellner, ensuring the paste exhibited the necessary high recovery rate for self-supporting structures. (All these geopolymer materials are distributed by Xatico in Europe).

A significant contribution is the use of Computational Fluid Dynamics (CFD), a novel application for geopolymers, to model material flow inside a custom-built 3D printer and fine-tune parameters for reliable extrusion. The optimized process successfully printed complex prototypes that, after thermal curing, reached 34 MPa in flexural strength, and 36 GPa in hardness, surpassing the cast material.

Furthermore, a Life Cycle Assessment (LCA) confirmed the geopolymer 3D printing is consistently more energy-efficient and sustainable than traditional methods, marking a significant step toward greener advanced industrial applications.

Abstract:

To determine the nature of the Carbunculus, we used an unexpected discovery from the GEOCISTEM program. During a meeting in Cagliari (Sardinia) in September 1996, we were able, together with the geologists, to visit the volcanic tuff quarry of Paringianu, exploited to extract ashlar. The local volcanic context is constituted by ignimbrites and rhyolites. The tuff is very indurated, i.e. it is solid. It is composed of plagioclase, potassium feldspar, pyroxene, a vitreous matrix and montmorillonite. It was sampled for analysis. During the visit, we saw a curiosity for the specialists of volcanic materials: while some tens of meters away, hard tuff was extracted, geologists showed us an unexploited area of the quarry. And with good reason: the stone had the same composition as the well indurated rock and it contained crystals of the same dimensions, but it disintegrated into sand, when we passed the nail or the finger over it. They explained to us that during the cooling of the volcanic layer, which must be done slowly for the rock to harden, a sudden degassing in this layer of tuff left columns through which the gases escaped: the stone did not have time to have a good cementing when it cooled. This showed the degree of cohesion between the two types of stone: one cooled slowly to acquire some consistency, while the degassing made the other a soft and not very indurated rock (Carbunculus). According to the geologists who accompanied us to the site, the difference in induration between two rocks of similar composition is a common phenomenon. By observing the degassing columns, we could see that they were vertical and that they created a small system of veins which vertically crossed the entire tuff layer from the bottom to the circulation floor. This was approximately one man’s height, and these ducts were a few centimeters wide. This phenomenon is known as “gas pipe”.

Résumé:

Pour déterminer la nature du Carbunculus, il faut se servir d’une découverte inattendue du programme GEOCISTEM. Durant une réunion à Cagliari (Sardaigne) en septembre 1996, nous avons pu, avec les géologues, visiter la carrière de tuf volcanique de Paringianu, exploitée pour en extraire de la pierre de taille. Le contexte volcanique local est constitué d’ignimbrites et de rhyolites. Le tuf est très induré, c’est-à-dire qu’il est solide. Il se compose de plagioclase, de feldspath potassique, de pyroxène, d’une matrice vitreuse et de montmorillonite. Il fut échantillonné à des fins d’analyse. Durant la visite, nous avons vu une curiosité pour les spécialistes des matériaux volcaniques: alors qu’à quelques dizaines de mètres, on extrayait du tuf dur, les géologues nous montrèrent un endroit inexploité de la carrière. Et pour cause : la pierre avait la même composition que la roche bien indurée et elle contenait des cristaux de dimensions identiques, mais elle se délitait en sable, quand on y passait l’ongle ou le doigt. Ils nous expliquèrent qu’au cours du refroidissement de la couche volcanique, qui doit se faire lentement pour que la roche durcisse, un brusque dégazage dans cette couche de tuf laissa des colonnes par lesquelles les gaz s’échappèrent : la pierre n’a pas eu le temps d’avoir une bonne cimentation en se refroidissant. Cela montrait le degré de cohésion entre les deux types de pierres : l’une l’une s’est refroidie doucement pour acquérir une certaine cohérence, tandis que le dégazage faisait de l’autre une roche tendre et peu indurée (Carbunculus). D’après les géologues qui nous accompagnaient sur le site, la différence d’induration entre deux roches de composition semblable est un phénomène courant. En observant les colonnes de dégazage, on pouvait voir qu’elles étaient verticales et qu’elles créaient un petit système de veines lesquelles traversaient verticalement toute la couche de tuf depuis le bas jusqu’au sol de circulation. Celle-ci faisait approximativement une hauteur d’homme, et ces conduits étaient larges de quelques centimètres. Ce phénomène est connu sous le nom de « gaz pipe ».

Pyramids (1) Are Pyramids Made Out of Concrete?
Pyramids (2) The evidences
Pyramids (3) The formula, the invention of stone
Pyramids (4) Videos and book
Pyramids (5) FAQ for artificial stone supporters
Pyramids (6) Deep misleading publications by geologists

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. These publications are draped in scientific impartiality when this is not the case. Here we point out their fatal flaws. Unfortunately, critics relying on said papers persist by pointing out the following three geological studies as the ones that restore the truth. It is time to put an end to this pseudo-science.

1. Dipayan Jana never actually examined the “Lauer Sample”
2. Another major misleading paper by James Harrell and Bret Penrod
3. The fatal flaw failure of geologist Robert Folk and petrographer Donald Campbell

1- Dipayan Jana never actually examined the “Lauer Sample”

Petrologist Dipayan Jana, of CMC-Materials Inc., in the USA, presented a paper at the 29th ICMA Conference in Quebec, Canada, titled “The Great Pyramid Debate” and later published his information in the Proceedings of the 29th Conference of Cement Microscopy, Quebec, Canada, May 20-24 (2007), pp. 207-266. He critiques my scientific findings as well as those of my colleagues, Materials Scientist M. W. Barsoum et al., Microstructural Evidence of the Reconstituted Limestone Blocs in the Great Pyramids of Egypt, Journal of the American Ceramic Society, 89 (12), 3788-3796 (2006)]. Here I will show the fatal flaw in D. Jana’s said work. We start by considering the target sample.

A. What is the Lauer sample?

The controversy concerns the analysis performed on a sample of the Great Pyramid of Cheops entrusted to me by the eminent French Egyptologist Jean-Philippe Lauer in 1981, and on which I have made analyses, publications and conferences. It is defined in the literature under the name of the “Lauer sample”. It is a piece of interior casing of the pyramid, made of limestone material, covered with a white man-made coating of calcium phosphate (hydroxyapatite) 1 mm thick and a red-brown iron oxide paint. See photo of the original Lauer sample from 1982 in Figure 1.

Figure 1: The Lauer sample. Photo taken in 1982.

Parameters for authenticating the true Lauer sample include its 4500-thousand year-old white coating and red-brown paint, and its dimensions.

B. Why did D. Jana test a fake sample instead of the Lauer sample?

D. Jana receive a piece of the “Lauer sample” from the American geologist specializing in the quarries of ancient Egypt, James Harrell, now Emeritus Professor at the University of Toledo. J. Harrell is a geologist opposed to the theory of agglomerated stone; we sent him the Lauer sample and his conclusions are obviously the opposite of those of our team of scientists. He returns what he claims is left of it, a severely damaged sample. However, years later he provides a sample of what is supposedly remnants of the Lauer sample to D. Jana. Thus, Jana calls the Lauer sample the “Lauer-Harrell” sample in his study (Figure 2) published in the Proceedings (see above).

Figure 2: The “Lauer-Harrel” blue sample received by D. Jana.

Page 213: “The Lauer-Harrell was a solid 25 × 45 mm sized, blue epoxy impregnated saw-cut section of a piece, larger than the Lauer-Campbell sample…”

The whole context of the study, described in Figures 12, 13, 14 on pages 252, 253, 254 of the Proceedings, shows that it is a vertical section (in thickness) and that it is not obliquely cut. The dimensions are: 45 mm wide and 25 mm thick.

However, the original thickness of the Lauer sample is 15 mm (see in Figure 3). In contrast, the “Lauer-Harrell” sample supplied by Harrell to Jana is 25 mm thick.

By deduction, the thickness of Jana’s sample proves that it could not have been the authentic Lauer Sample.

Figure 3: The thickness of the genuine Lauer sample compared with the sample studied by D. Jana.

C. In D. Jana’s study, there is no coating. So, is this a FAKE?

Jana observes that the sample he has received from Harrell does not exhibit the distinctive coating of the Lauer sample. The coating is a critically important distinguishing trait that characterizes the authentic “Lauer sample”. In the Proceedings, Jana mentions three times (pages 213, 229 and 255) on the non-compliance of the sample with the scientific literature. Despite the doubt, and despite the sample mysteriously and impossibly growing 10 mm in thickness, he continues his studies claiming that the Lauer sample is natural limestone.

So:

• Page 213: “Neither piece contained the white coating or the red paint that was originally mentioned by Davidovits, which was reportedly (by Harrell) accidentally removed during the preparation of the thin section”.
• Page 229: “Although the actual “coating” was not present in the Lauer sample of this study (reportedly accidentally removed…)”.
• Page 255: legend of Figure 15: “Despite the absence of this coating…”.

J. Harrel published a study in 1993 on this white coating (see in Figure 15, page 255, in the Proceedings), but in 2007 he sent D. Jana a different piece of limestone not covered with this characteristic coating, calling it nonetheless the “Lauer sample”.

It is hard to imagine a competent, skilled geologist accidentally removing the coating from the Lauer sample when preparing a thin section of it. The coating is very firmly welded to the stone and does not flake off. It is not a paint, and the impregnation of blue epoxy is used to prevent such accidents. J. Harrell has made too many thin sections in his professional life to destroy a major archaeological sample. If it does not have its characteristic coating, its origin is doubtful.

CONCLUSION:

The most logical explanation is that the sample D. Jana studied was a piece of natural limestone from Egypt’s Tura quarry 25 mm thick (instead of 15 mm) without the white artificial coating of calcium phosphate.

It is therefore a forgery. Jana’s study of the rock passed off as the “Lauer Sample” can no longer serve as a reference. Jana is, therefore, obligated to retract his paper in good conscience, and Harrell must explain or accept responsibility for his actions.

2- Another major misleading paper by James Harrell and Bret Penrod

A chapter of my book “Why the Pharaohs built the Pyramids with Fake Stones” shows another serious misleading conduct published by Harrell and Penrod. See in Appendix B, page 265 (2017 edition) or 263 (2009 edition). In chapter 7, I describe the Mokattam Formation at Giza comprised of layers of middle Eocene limestones upon which the Great Pyramids of Giza are built. The Mokattam Formation comprises two distinctly different layers of fossil shells limestone: a hard gray upper bed on which the pyramids are built, and a friable marly yellowish bed. It was this friable, earthy deposit (concrete grade) limestone that was exploited to build the bulk of the Great Pyramids of Giza (see the diagram in Figure 4).

Figure 4: cross section of the Giza plateau, the Mokattam Formation and the quarries.

Despite this basic well-published geological knowledge, and clearly visible on the two outcrops located near the monuments, the American geologists J. Harrell and B. Penrod dispute the theorem of the artificial manufacture of limestone blocks, as follows.

In their article [Harrell, JA and Penrod, BE, The Great Pyramid debate; evidence from the Lauer sample, Journal of Geological Education, vol. 41, No. 4, pp. 358-363, 1993], they state: “… Our objection to the geopolymeric process (agglomerated stone process) has to do with disaggregating limestone by soaking it in water — it does not work! We soaked the Mokattam limestones whose composition is given in Table 1 for seven weeks and after this time the samples were just as hard and solid as the day we first immersed them…”

For their demonstration, Harrell and Penrod instead removed hard limestone from Gebel Mokattam, 20 km from the pyramids, on the other side of the Nile (see Table 1 cited in their said publication). That is, they should have sampled from the concrete-grade limestone quarries located in Giza, in the wadis or in the Sphinx trench at the foot of the pyramids. It is well known to all experts on Egyptian geology, and well-published in Egyptological literature, that these two Giza sites (the wadi and the trench in which the Sphinx sits), are where rock materials for the Great Pyramids of Giza are derived. The sample they soaked in water does not come from the Giza pyramid site at all. It is taken from a non-applicable location, the modern quarry of hard limestone behind the Citadel of Gebel Mokattam in Cairo, 20 km east of the Giza pyramids, on the other side of the Nile.

How can professionals consider that the Mokkatam geological formation of Giza is absolutely identical to the geographical designation Gebel Mokattam? Why not have just taken a piece of stone in Giza, on the site of the pyramids? Why make it so complicated? J. Harrell hopes to fool the public, collecting a rock sample of different origin, but bearing the same name, to demonstrate that our theory is false.

C- The fatal flaw of geologist Robert Folk and petrographer Donald Campbell

This is not the first time that geologists have published studies containing serious failures. Thus, immediately after arriving on the Giza plateau in January 1990, the American geologist R. Folk and petrologist D. Campbell observe blocks of stone which seem to them to be natural limestone. They publish an article in Journal of Geological Education [R.L. Folk and D.H. Campbell, Are the Pyramids built of poured concrete blocks, Journal of Geological Education, Vol.40, pp. 25-34 (1992)].

In my book “Why the Pharaohs built the Pyramids with fake stone”, page 268, I reproduce the original text: “Within the first minute at Cheops pyramid, we knew that the pyramids were built of real limestone blocks, not of concrete (reagglomerated stone)….”

We also read:
“… we feel it is the duty of professional geologist to expose this egregiously absurd archeological theory before it becomes part of entrenched pseudo-science… We believe that had Davidovits had any understanding of basic geologic principles and understood the implications of simple geological evidence at Giza, he would have realized that this geopolymer theory had no basis in fact...”

Upon arriving at Giza, Folk and Campbell go directly to the northeast corner of the Great Pyramid of Cheops. In their article, they do not explain the reason for this choice. There, they find natural limestone (see photo in Figure 5). In 1983, the American Egyptologist Mark Lehner mentions the existence of this natural geological layer, going up to 4 meters above the base of the pyramid, in this northeast corner. But R. Folk and D. Campbell ignore this essential information. I publish my answer in a renowned journal “J. Davidovits, The Great Pyramid debate, Concrete International, Vol. 14, No. 2, pp. 17-18, (1992) ”.

Figure 5: the natural limestone at the northeast corner of Cheops Great Pyramid.

Soon after, I receive a letter from R. Folk dated February 18, 1992, which reads:
“…I was impressed by your reasonable and interesting letter in Concrete International, Feb. 1992… Your argument that the lower two courses of Khufu (Cheops), on the east face, are in place bedrock is intriguing and I must admit was a new thought to me. This morning, thanks to your citation, I went over and read Lehner (1983) on Khufu (Cheops) and he does indeed show the NE corner of Khufu to be bedrock in his sketch. Our photo was of that corner. So I concede that, on the North-East corner, you are correct as the bedrock idea had not entered my head at the time we were there…”

Robert L. Folk, renowned for writing the standard limestone geologists refer to, admitted that he has no basic knowledge of the geology of the Giza plateau when he makes his survey and triumphantly proclaims: “… Within the first minute at Cheops pyramid, we knew that the pyramids were built of real limestone blocks, not of concrete (reagglomerated stone)…”

Ironically, the geologists do not differentiate between a natural outcrop of the plateau and blocks of pyramids!!! How to take this study seriously when all tourists can readily see this distinction?

The article by Folk and Campbell, published 30 years ago, is still cited today by those whose purpose it is to discredit my research. They do not know that Folk confessed his error.

Last year, we had a big Geopolymer Camp. 2/3 of the participants were professionals from the industry and business pioneers, 1/3 were academics. This event is now the best to create your network.

We have opened the registration by now in February and early birds have already signed up.

We have a limited number of seats (fewer than 95), so I strongly suggest you do not wait too long to join us. Chances are that, by the end of May, there will be few seats left.

We want to keep this event small in size but big in quality (good knowledge shared and interesting people to meet), as most of you already know, in order to emulate sharing, discussions, meetings, so every participant shall have a satisfying event.

As always, we keep the registration fees to a minimum of 70 Euro (approx. 75 US $) for advance payment, just to cover the costs for organization, lunches, coffee and the like, etc.

FOR NEWCOMERS: If you are new to the world of geopolymers and you don’t know how to begin, what raw materials to select, how to manufacture geopolymers, what are the good practices, and looking for a good understanding of this chemistry, the Geopolymer Institute organizes a Tutorial / Workshop (a short course) for beginners at a very low cost on the first day, Monday, which takes place before the beginning of the Geopolymer Camp. It is aimed at providing a dedicated introduction to geopolymer technology and is illustrated with appropriate laboratory demonstrations. Participants will learn how to make 3 standard recipes for ceramic like application and for cement like use. You will be given the exact step by step recipes, the list of raw materials and chemical ingredients with the name of their suppliers. After this workshop, you will be ready to start.

Tutorial fees: 360 Euro (approx. 380 US $) for advanced payment. See the program at the GeopolymerCamp web page:

Why Alkali-activated-materials AAM are not Geopolymers

Script of the Video series available
at the Geopolymer Institute, Why-AAM-are not GP and on YouTube.

Many scientists and civil engineers are mistaking alkali activation for geopolymers, fueling confusion, using them as synonyms without understanding what they really are.
To sum-up: Alkali-Activated Materials (AAM) are NOT Polymers, so they cannot be called Geo-Polymers. AAMs are hydrates and Geopolymers are polymers. Geopolymers are NOT a subset of AAM because they are not a calcium hydrate alternative (no NASH, no KASH). Geopolymer is not a hydrate, because water does not participate in the structuration of the material. They belong to two very different and separate chemistry systems (a hydrate/precipitate that is a monomer or a dimer versus a true polymer). Those who claim that both terms are synonyms are promoting a misleading scientific belief.

In my four keynotes at the Geopolymer Camp (2014-2017), I explained why Alkali- Activated-Materials are not Geopolymers, or why alkali-activation is not geopolymerization. We have selected all the sequences that had been dedicated to this issue in the GPCamp-2014, 2015, 2016 and 2017 keynotes. These videos are titled: Why Alkali- Activated Materials are NOT Geopolymers. You will finally understand why there are two different systems.

A recent scientific paper describes Novel hybrid organic–geopolymer materials prepared through an innovative synthetic approach based on a co-reticulation in mild conditions of epoxy based organic resins and an MK-750-based geopolymer inorganic matrix.
A high compatibility between the organic and inorganic phases, even at appreciable concentration of resin, was realized up to micrometric level. The new synthetic approach is based on the incorporation of the organic resin to the geopolymeric matrix suspension when both polymerization reactions are not yet completed. On gets good compatibility between the organic and the aqueous inorganic phases thanks to the numerous hydroxyl tails formed during the epoxy ring opening reaction that make the organic phase “temporarily hydrophilic” increasing the compatibility with the aqueous inorganic phase.
These new hybrid organic-geopolymer materials present significantly enhanced properties. This research is carried out at Dipartimento per le Tecnologie – Facoltà di Ingegneria, Università di Napoli ‘Parthenope’ with the collaboration of Depart. of Chemistry, University Frederico II, Napoli.

Dr. Giuseppina Roviello will present a Keynote paper on this topic at the Geopolymer Camp 2013.

In a display of industry-leading technology and innovation, Rocla has recently debuted its latest, award-winning capability – the successful use of geopolymer materials in commercial scale production. While many of its competitors have tried to produce geopolymer products on a large-run scale, Rocla is the first to successfully bring a product to market, and also the first to have the stand-alone capability to do so. With the environmental benefits of geopolymer technology destined to bear fruit for future generations, the nature of Rocla’s first commercial-scale product is a little ironic; their ‘world first’ production run, which was undertaken in Canberra, involved the production of 3,000 components for a customer’s patented crypt system to be supplied to the Woronora Cemetry Trust in Sydney.
The project required 2500 tonnes of geopolymer material, which was used to manufacture three different crypt components, each finished to a high standard, and exacting dimensions. While the client was delighted with quality of the end product, mastering the art of working with geopolymer did present some challenges for the Rocla team to overcome.
“Getting a perfect finish on each component required a lot of dedication and hard work from our team – right from the R&D phase through to the manufacturing and finishing, we’ve worked incredibly hard to bring this project to fruition and produce a top quality product”, says Wayne McGovern, Rocla’s ACT Area Manager. With a delighted client now eager to extend their use of the new crypts, the team’s efforts have undoubtedly paid off and they are now looking towards the future to extend the range of geopolymer products they are able to offer. Adding to the buzz surrounding the product is its recent win at the prestigious, international Fletcher Building Innovation Awards, which recognise Fletcher Building’s business units that excel at innovating. The geopolymer project took out the top prize for best use of technology in innovation in early November.

I first visited ROCLA in Sydney 12 years ago, in January 1999. The company wanted to develop geopolymer-based sewage pipes. Rocla’s scientists J.T. Gourley and G.B. Johnson, presented their results at the Geopolymer’ 2005 conference in Saint-Quentin (Development in geopolymer precast concrete, pages 139-143 in the Proceedings).
With this new application, it is the second commercial success for a Geopolymer 2005 conference participant. I already mentioned the first one in my Geopolymer Camp keynote “State of Geopolymer 2012“, last July: half a million geopolymer pavement bricks manufactured in India under the supervision of Sanjay Kumar from Council of Scientific & Industrial Research, Jamshedpur, India.

Congratulations.
