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.

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.

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.

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.

STOP promoting fly ash-based cements !

by Prof. Dr. Joseph Davidovits, 

Geopolymer Institute, Saint-Quentin (France)

A continent is on fire. Both Australia and California have never experienced such an inferno. More and more citizens are blaming the climate change (that is CO₂ emissions) responsible for this. But the governments of Australia, along with the U.S., Russia, Brazil, China, India, Poland, South Africa and also Germany – where coal mining and coal-power plants are significant industries and with powerful lobbies – are entrenched and want to stick to their coal policy and business.

Fly ash-based cement is supporting the burning of coal:

The demand for coal in electricity power plants is steadily increasing in the world and consequently generates more and more fly ash. Power plants are lobbying the cement and building industry with so-called low-CO₂ fly ash-based cements. The fact that fly ash is used to make building materials is an excuse to increase coal production. Therefore, any development and implementation of fly ash-based cement is supporting the burning of coal in the production of electricity and increasing CO₂ emission.

But, do you know that the manufacture of 1 metric tonne of fly ash is generating 33 metric tonnes of CO₂ emission? This fact has been overlooked by all experts, including United Nations Environment experts and myself. Indeed, the burning of 10 t Carbon (C=12 g/mol.) produces 36.66 t of CO₂ (CO₂ = 44 g/mol.). But the burning of coal generates 10% by weight of fly ash. In other words, 10 t coal are producing 1 t fly ash and emit 33 t CO₂.

All taken-for-granted ideas and promotional slogans about low-CO2 cements based on fly ash are totally wrong:

Consequently, 1 t of fly ash-based geopolymer cement containing 50% by weight of fly ash, should be associated with 16.5 t of CO₂ emission. Accordingly, 1 t of blended-OPC containing 50% by weight of fly ash, should also be linked to an additional 16.5 t of CO₂ emission. These numbers seem extravagant but they do represent scientific reality, particularly if we compare them with those numbers published in the past for geopolymer cement: 0.2 t CO₂/1 t GP-cement, as well as for Portland cement: 0.9 t CO₂/1 tonne OPC. All taken-for-granted ideas and promotional slogans about low-CO₂ cements based on fly ash are totally wrong.

Experts are stating that this CO₂ does not count because it has already been spent in the production of electricity. But we understand that this production has no future because it is harmful to the global climate. Therefore, the production of fly ash-based cement is not a long-term solution. Admittedly, the material is available and sometimes stored in large quantities. But I think it is not suitable for mass production, only for local niche markets or technical specialties.

Therefore, we should stop promoting coal-fly ash-based geopolymer cements. The solution is to develop and implement geopolymeric systems relying solely on geological resources, such as Ferro-sialate geopolymer cement and the like.

The geological raw material is available worldwide and long-term stability has been demonstrated. There is no reason why scientists around the world should not be working on it. See our recent article on Ferro-sialate Geopolymers in the Geopolymer Institute Library at Technical Paper Nr27 Ferro-sialate. A special session will be dedicated to this topic at the next Geopolymer Camp 2020, July 6-8.

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.

The Geopolymer Institute is proud to sponsor the GeoMongol Rally Team. Liza, Marina and Andrey Dudnikov left the Geopolymer Camp and Saint-Quentin on Thursday July 13 (see on the photo with Prof. J. Davidovits). These Russian geopolymer experts and entrepreneurs are participating in the 2017 Mongol Rally, an 8-week, 16,000 km long crazy adventure departing from London, UK, on the route through several European and Asian countries.

Follow them and support their journey on Instagram #geomongol and read more on the GeoMongol website (read all details and buy stuffs to help raising money for charity). Track the itinerary in real time at mongolrally.iridium360.ru

After 6 weeks and 18700 km, they did it ! But they have to come back !!! In total, they travelled 26500 km (from Tcheliabinsk, Russia, to London, UK, then London, UK to Oulan-Bator, Mongolia, then back to Tcheliabinsk, Russia) and crossed 21 countries. What an adventure. And they made some geopolymer concrete too…

You may wonder who they are ?

The Dudnikovs (Marina Dudnikova + Andrey Dudnikov), together with Italian expert Alex Reggiani,  have created the company Renca in Russia to market true geopolymer cements all over the world (they are presently focusing on Dubai). They refuse to fall into the trap of cheap, low-tech, bad quality alkali-activated cements. They made the choice of manufacturing high quality geopolymer products with selected raw materials. Therefore, they are developing innovative geopolymer cement processes with in-house designed equipment. They don’t target at all-purpose mass markets, but into problem solving applications, yet with easy to implement solutions. For example, they are commercializing special geopolymer concretes for 3D printing (together with ApisCor), or designing an innovative Mobile Automatic Mixing System for manufacturing geopolymer concrete on the construction site, or offering a smart solution for fire protection in buildings with sprayed geopolymer foam, or passive cooling and reducing air conditioning energy…

They are pioneers like the Wagners in Australia, willing to seize opportunities and true entrepreneurs willing to take risks. Their participation to this eccentric and fascinating rally illustrates their mindsets. The Geopolymer Institute sticker on their car will travel through Europe and Asia.

Special topics of interest:
– Tutorial Workshop (short courses) for Newcomers, on Monday;

False Values on CO₂ Emission for Geopolymer Cement/Concrete Published in Scientific Papers

Adapted from the article originally published in Elsevier’s internet site “Materials Today” at Environmental Implications of Geopolymers, 29 June 2015. See also the presentation at the Geopolymer Camp 2015. See also the news Virtual Journal on Geopolymer Science .

LCA of commercialised geopolymer cement/concretes are seldom. This is due to proprietary reasons. Presently they are based on Type 2 slag/fly ash/alkali-silicate system (see Technical papers #21, #22, #23 in the Library). Geopolymer Type 2 concrete and standard Portland concrete are similar in non- binder materials used and behaviour after production; there is some dilution of the benefits when measured over the full life cycle (LCA). The greenhouse gas emissions during the life cycle of Geopolymer Type 2 concrete are approximately 62%-66% lower than emissions from the reference concrete. The Type 2 geopolymer cement has ca. 80% lower embodied greenhouse gas intensity than an equivalent amount of ordinary Portland cement binder used in reference concrete of a similar strength, confirming the data published by the Geopolymer Institute, where the reductions are in the range of 70 % to 90 % (see Technical paper #21). These values do not include any additional external constraints like transport from or to the utility. They reflect the actual potential as soon as industrialization starts in full swing.

On the opposite, several published scientific LCA papers claim that, in terms of CO₂ emission, geopolymer cement was not better than Portland cement, and worse for other parameters. These statements are based on methodological errors and false calculations of the CO₂ emission values for geopolymer cement/concrete. The problem is that these false values are taken for granted by other scientists without any further consideration.

The present paper “False Values on CO₂ Emission for Geopolymer Cement/Concrete Published in Scientific Papers” cites and explains the methodological errors and false calculations.

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. See our News dated of October 14, 2014, 70,000 tonnes Geopolymer Concrete for airport.
This project marks a very significant milestone in engineering – the world’s largest geopolymer concrete project. 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. For technical details read the paper by Glasby et al. (2015), EFC Geopolymer Concrete Aircraft Pavements at Brisbane West Wellcamp Airport, in our Library, Technical paper #23 GP-AIRPORT.

Prof. Joseph Davidovits’ visit to the Toowoomba-Wellcamp-Airport.

On October 3, 2015, Joseph and Ralph Davidovits flew from Sydney Airport to Toowoomba-Wellcamp-Airport, for a visit to the company Wagners.

Prof. Joseph Davidovits’ visit to the Global Change Institute, Brisbane, Queensland, Australia.

On October 7, 2015, Joseph and Ralph Davidovits drove with Tom Glasby and Russell Genrich, company Wagners, from Toowoomba to Brisbane. Our News dated December 10, 2013, was titled World’s first public building with structural Geopolymer Concrete. It introduced the world’s first building to successfully use geopolymer concrete for structural purposes, the Global Change Institute, University of Queensland, Brisbane, Queensland, Australia. The 4 story high building, for general public use, comprises 3 suspended geopolymer concrete floors involving 33 precast panels. They are made from slag/fly ash-based geopolymer concrete coined Earth Friendly Concrete (EFC), a Wagners brand name for their commercial form of geopolymer concrete.

Last year (October 14, 2014), our News was titled 70,000 tonnes Geopolymer Concrete for airport; it presented company Wagners’ newly developed geopolymer concrete EFC in the construction of the Brisbane West Wellcamp Airport (BWWA), Toowoomba, Australia, which became fully operational with commercial flights operated by Qantas Link in November 2014. 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, 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, was used for the turning node, apron and taxiway aircraft pavements, and cast in place with the slip form paving machine displayed below.

IMPORTANT: We are changing the format of our Webinar – Q&A session only!

Outline of the talk:

For this Webinar Fall 2014, we have decided to set up a unique Questions and Answers (Q&A) session. Join Professor Joseph Davidovits and get your chance to ask any questions on Geopolymer Chemistry and Technology. He will answer to questions either sent in advance or directly from the audience, live from his office, and stay online up to 3 hours until relevant topics have been discussed.

We change the format because the videos of the last Webinar Spring 2014 are still available at this web page Video – Webinar Spring 2014: Geopolymer Web Workshop, Apr. 8-9. They have been now watched a thousand of times and been acclaimed by many as the best and straightforward introduction to geopolymers for all audiences (including students, scientists, engineers, business men, enthusiastic…). So, we strongly engage your attention to watch again these videos before attending the webinar and prepare asking your questions.

You will have two ways of asking questions:

1. Complex questions that need certain time to read and study. You can send Professor Joseph Davidovits some texts, pictures or PDF and ask for his advices. He will try to answer your query as best as possible with regard to the audience interests. Please, send in advance your question or comments as a PDF file with graphs and images not exceeding 5 MB in total at the bottom of this page.
2. Simple short questions. They can be asked during the webinar session. Just, type in your question in the chat field of the GoToMeeting software. You can also write your question in advance at the bottom of this page.

Obviously, you may attend the seminar without having to send any question. It is free for anybody to listen and learn, provided you register. Therefore, we are inviting you to participate, to share the spirit of this event, and hope to have you on line during this Geopolymer Webinar Fall 2014.
