Geopolymer 3D Printing: When Rheology Meets Robotics
Keynote by Dr. Abrar Gasmi

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.

. This book
• Brings new insights on the study of well-known Archaeological sites
• Examines the use of Geopolymers
• Solves open problems in the analysis of Tiwanaku and Easter Island

The book presents the study (with recent updates) on Ancient Geopolymers in South America and Easter Island regions, exploring the artificial nature of the volcanic rocks used in the construction of Easter Island’s statues. Contrary to the belief that the statues were carved and transported, Davidovits suggests they were made on-site using geopolymer technology. He proposes that this knowledge came from Amerindians from the Andes, specifically the Tiahuanaco region near Lake Titicaca. The book is divided into two parts: the first examines geopolymeric artificial stone technologies in the Andes, and the second establishes a connection between these technologies and Easter Island, 3,700 km away. Davidovits’ research includes geological expeditions, SEM analysis, petrography, and a comprehensive review of international literature. It is intriguing to observe that in both cases, Pumapunku /Tiwanaku in the Andes and Easter Island, volcanic rocks are involved which contain biological carbon. These discoveries undeniably support the theory of geopolymeric artificial manufacturing, challenging traditional archaeological views.

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. AAM and Geopolymers 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. Learn why by watching these four videos.
“Non-activated geopolymers” are the only TRUE geopolymers that provide the excellent properties you are expecting. AAM kills polymeric reaction.

Geopolymers vs. AAM: Understanding the Crucial Differences

Summary: Geopolymers are not Alkali Activated Materials (AAM).
AAMs are characterized by their hydration process and are not polymers. Therefore, they cannot be called geopolymers. Geopolymers, on the other hand, are polymers and not hydrates. Consequently, the terms NASH or KASH are irrelevant because geopolymers are polymers, not hydrates. It is a significant scientific error to claim that polymers and hydrates are similar. Attempting to create a polymer using the mix design of a hydrate will result in failure (cracking, shrinkage and efflorescence). Conversely, following the kinetics of a polymer when making a geopolymer will result in success.
There is no controversy. You have been misled by people who lack a proper understanding of polymers. You have been faithfully following and copying their wrong mixes and getting bad results.
Everything is proven with solid scientific evidence against fake science.

Video description: This video is an excerpt from a 3-hour workshop on geopolymer processing. Buy the Geopolymer Bundle (click here).
It addresses common misconceptions about geopolymer cements and explains why many attempts to produce geopolymer cements have failed to achieve the superior properties that are often cited in the scientific literature.
The presenters argue that geopolymers are not alkali activated materials (AAM) and highlight the fundamental differences between the two. They emphasize the importance of understanding polymer chemistry for successful formulation.
The video critiques common errors in the scientific literature, particularly those propagated between 2003 and 2019, that have led to confusion in the field. It explains why treating geopolymers as hydrates (NASH or KASH) is incorrect and provides evidence from infrared spectroscopy and the role of water to support this claim.
The presenters emphasize the importance of proper terminology and understanding, pointing out that geopolymers are true mineral polymers, not hydrates or precipitates.
This informative video aims to clear up misconceptions and provide a solid foundation for those interested in working with geopolymer cement, ultimately promoting a better understanding and more successful implementation of this innovative material in construction and engineering.

Other videos

In his four recent keynotes at the Geopolymer Camp 2014, Geopolymer Camp 2015, Geopolymer Camp 2016 and Geopolymer Camp 2017, Prof. J. Davidovits 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 new videos are titled: Why Alkali-Activated Materials are NOT Geopolymers. You will finally understand why they are two different systems.

Part 4 (new 2017): NASH / KASH is an invalid terminology

In 2016, a paper published by a group of scientists determined that there is no presence of NASH or KASH in geopolymer cement (see part 3 below). In this short excerpt, Prof. Joseph Davidovits explains this result by the true polymer nature of geopolymer chemistry. You will learn what true NASH and KASH are, and in which context they are actually used. AAM and geopolymer cement (wrongly shorten by some as “geopolymers”) are two very different and separate chemistry (a hydrate/precipitate that is a monomer or a dimer versus a true polymer). None is a subset of the other or its derivative which leads to confused interpretations.

Part 3: AAM are not polymers, so they cannot be called “geopolymers”

Prof. Joseph Davidovits emphasizes the fact that Alkali Activated Materials (AAM) are not polymers, so they cannot be called “geopolymers”. He presents what scientists are now writing about this issue. They now agree with proven facts that it is a big scientific mistake to use AAM and geopolymer as synonyms, and people shall stop doing so. Geopolymer cement is not a CSH derivative; therefore, scientists are now stating that applying the CSH terminology from Portland cement is not only inappropriate, but also calling them NASH and KASH is totally wrong. Those who purposefully use and propagate these misleading languages delude the understanding of the true chemical reactions that really occur (never a hydrate or a gel, but a polymer), resulting in confused interpretations.

Part 1 (2014): AAM are not geopolymers, two different chemistries

Prof. J. Davidovits explains the main differences between AAC (Alkali-Activated Cement or Concrete), AAS (Alkali-Activated Slag), AAF (Alkali-Activated Fly Ash) and Slag-based Geopolymer cement, in terms of chemistry, molecular structure, long-term durability. In a second part, on hand of the industrialization of Slag/fly ash-based geopolymer cement/concrete implemented by the company Wagners, Australia, he focuses on the results provided by the carbonation testing data obtained for ordinary Portland cement, AAS and EFC (Slag/fly ash-based geopolymer). The tests were carried out at the Royal Melbourne Institute of Technology RMIT in Australia. Geopolymer behaves like regular Portland cement, whereas AAS gets very bad carbonation results.

Part 2 (2015): Clarifying statement about all the false ideas and assertions

Prof. J. Davidovits makes a clarifying statement about all the false ideas and assertions written by several alkali activated materials scientists (incorrectly using the word “geopolymer” for marketing purpose in place of AAM) and blindly imitated by others. He explains why it is a true polymer with a well-known and understood chemistry (as opposed to those who claim it is a “gel” of unknown character), mentions the historicity and discovery of geopolymer chemistry, the real contributions of Glukhovsky and what he really wrote about geopolymers. He develops the range of actual industrial applications that goes far beyond cement made out of wastes…

In his keynote “State of the Geopolymer R&D 2023”, Professor Joseph Davidovits provides a comprehensive review of the advancements in geopolymer science and applications over the past year. He begins with discussing ongoing research into the fundamental geopolymerization process and new discoveries around acid-based geopolymerization. Moving into practical applications, Prof. Davidovits examines the development of super high strength metakaolins and how geopolymers can help mitigate global warming through their lower carbon footprint compared to Ordinary Portland Cement. Other timely topics covered include the role of geopolymers in sustainable water resources management and repairing critical infrastructure like roads and pavements damaged by floods. The keynote also talked about progress with 3D printing using geopolymer binders to create strong and stable ceramic-like materials. A highlight is providing details on the world’s first 3D printed house in geopolymer concrete. Lastly, Prof. Davidovits envisions future opportunities for geopolymers to enable more durable habitats for permanent settlements on the moon.

• (10:24) First Printed House – Fight Against the Nature, Alex Reggiani, Marina Dudnikova and Andrey Dudnikov (RENCA)

In April 2023, Geopolymer International, Renca and StrongPrint3D came together in Las Vegas, Nevada to pioneer the world’s first 3D-printed house made entirely from geopolymer cement. Despite the extreme heat and frequent winds in the Las Vegas desert, their teams worked tirelessly over several weeks, using large robotic printer equipment to layer the geopolymer cement to construct the house piece by piece directly on site. There were many challenges along the way, such as cement drying and setting quicker than expected in the hot weather. Adaptations had to be made like modifying cement mixtures. Heavy winds also disrupted prints on some days. However, through ongoing collaboration and adjustments to their process, the companies overcame these hurdles. Finally, they announced the successful completion of the fully 3D-printed house, proving the feasibility of building structures with this innovative method and opening doors to future sustainable housing applications using geopolymer materials.

Conference presented by Abrar Gasmi, a PhD student at University Picardie Jules Verne in France, titled “Additive Manufacturing of Ceramic Type Geopolymer For Complex and Tiny Objects.” A. Gasmi discusses her research into 3D printing geopolymer materials, which are environmentally friendly ceramic-like composites. She outlines the challenges in robocasting or extrusion-based 3D printing of geopolymers. A. Gasmi explains how the rheological properties of geopolymer pastes must be characterized to determine their suitability for the 3D printing process. A variety of potential anomalies are explored, from flaws in the initial geopolymer formula to issues that can arise during and after the printing process. She shares insights on developing an optimized geopolymer formula for 3D printing through rheological testing and characterization. She highlights some of the promising results thus far in additively manufacturing complex, small-scale geopolymer prototypes.

Abstract:

The studies carried out in 2015-2018 on the monumental stones constituting the Pumapunku site in Bolivia (South America) provide evidence that the stones are ancient artificial geopolymers. The two types of lithics under consideration are large platforms and ‘sculptures’ exhibiting characteristics that would have been extremely difficult, if not impossible, to achieve with the tools thought to be available to the Tiahuanacans’ of 1500-2000 years ago. For examples, big lithics exhibit perforations of unique characteristics. These holes, believed to be boreholes, are found in andesite artifacts. In number, they approach 900 perforations. The holes/perforations of 3 or 4 mm diameter could have been created with wooden dowels forced into the plastic geopolymer, as well as reed or copper tubes forced into the material in the same way cookie cutters remove the cookie from the dough. The paper also discusses other geopolymer lithics.

Abstract:

The studies carried out in 2017-2018 on the monumental stones constituting the Pumapunku site in Bolivia (South America) provided evidence that the stones are ancient artificial geopolymers (Parts I to III). To make geopolymer andesite stone, around AD 600 to AD 700, the builders could have transported an andesite stony material having the consistence of sand from the Cerro Khapia volcano site, and added an organo-mineral geopolymer binder manufactured with local biomass ingredients. They did not use the many quadrangular volcanic blocks, the famous “piedras cansadas”, the tired stones, which are still lying on both sides of the lake Titicaca. The present paper describes how the builders of Pumapunku / Tiwanaku exploited a natural volcanic andesite sand from the volcano Cerro Khapia, transported and stored it at the shore village of Iwawe, Stratum (V) in the excavation by Isbell & Burkholder, (2002). For the making of their andesite geopolymer monuments, they did not need to crush andesite rock. This andesite sand is similar to one of the pozzolana sands found in the best ancient Roman mortars and coined in Latin “carbunculus”, 2000 years ago.

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 ».

Abstract:

Concentrations of light elements using micro-PIXE and micro-PIGE reveal the elemental composition of the various materials used for the construction of the pyramids. Light elements (mainly Na, Cl and S) show a very heterogeneous distribution for the pyramid’s material in contrast with the extremely homogeneous distribution of these elements in natural limestone from quarries of Turah and Maadi and the bedrock of Saqqarah. The micro-PIXE elemental maps present new evidence for the application of a molding procedure.
