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…

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.

Geopolymers are NOT a subset of AAM because they are not a calcium hydrate alternative (no NASH, no KASH).

“We want to understand the basic behavior of the geopolymer matrix,” said Akono, “and we needed a supercomputer to carry it out and measure the response of a material from nano to macro level. Blue Waters provided great resources to bridge the gap with computing power.”

They used Blue Waters to produce a 3D framework that can be used to design strong geopolymer composites with a wide range of application including advanced ceramics, fire- and corrosion-resistant coatings and thermal barrier coatings, low-emitting materials…

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

Outline of the talk:

For this Webinar Spring 2017, we have decided to set up a 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 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 strongly engage your attention to watch again the previous webinars videos before attending the webinar and prepare asking your questions. 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…).

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 which is the best method anyway to get an answer.

The Virtual Journal on Geopolymer Science is a collection of already published research papers, curated by us, all relating to geopolymers. We intend to publish at least four issues per year, each issue being dedicated to a special theme. This critical review is the follow-up of the first issue, a feature article titled Environmental implications of Geopolymers, online on 29 June 2015. It has been written in compliance with a decision of Elsevier and Geopolymer Institute to join forces, distill and distribute the best research publications contained in their combined archives, through a series of Elsevier-Geopolymer Institute Virtual Special Issues on Geopolymer Science.

Much of the original research into geopolymers was conducted on calcined kaolinitic clay precursors known under the generic term of metakaolin. Although metakaolin reacts in alkaline as well as in acidic medium, the present issue focusses exclusively on the alkaline route on natural and synthetic metakaolin.

Webinar Spring 2016

This free webinar covers various aspects of the geopolymer science and applications. Yet, you will find a focus on geopolymer cement and concrete to celebrate its successful commercialization that raises a great interest all over the world.

1. Geopolymer definitions.
2. Real world and successful applications and commercialization.
3. Heat and fire-resistant geopolymer.
4. Why did it take 30 years to commercialize geopolymer cement?
5. Alkali Activated Materials are not Polymers, so they cannot be used as synonyms for Geo-Polymers!
6. The “good” geopolymer terminology and why using it opens its understanding.
7. Principles of geopolymer technologies (it is first a real “polymer”).
8. Fly ash-based geopolymer concrete: how to make a good one.

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.

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.
