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.

Joseph Davidovits, 12/01/2020.

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.

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.

There will be two sessions, one for the Eastern hemisphere and the day after for the Western hemisphere. Please, register to only one session.

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.

The last few years have seen spectacular technological progress in the development of geosynthesis and geopolymeric applications.

New state-of-the-art materials designed with the help of geopolymerisation reactions are opening up new applications and procedures, and transforming ideas that have been taken for granted in inorganic and mineral chemistry.

Since the discovery of the geopolymer chemistry by Prof. Joseph Davidovits (see also in the Library the scientific paper IUPAC 1976) this new generation of materials, whether used pure, with fillers or reinforced, is already finding applications in all fields of industry. These applications are to be found in the automotive and aerospace industries, non-ferrous foundries and metallurgy, civil engineering, cements and concretes, ceramics and plastics industries, waste management, art and decoration, retrofit of buildings, etc. One third of the recently updated book Geopolymer Chemistry & Applications is dedicated to geopolymeric applications. You may also go to the Geopolymer Library and download several papers, for example #21 Geopolymer cement review 2013.

Some of the geopolymer applications are still in development whereas others are already industrialized and commercialized. They will be listed in six (6) categories, namely:

Geopolymer Precursor

Geopolymer Resin, paint, binder, grout

Geopolymer cement, concrete, waste management, global warming

Applications with geopolymer cements and concretes are described in the section Geopolymer Cement with special emphasis on the introduction of user-friendly systems. It is striking to notice that Geopolymer cements manufacture emits 80 to 90% less CO₂ (greenhouse effect gas) than Portland Cement. See in GLOBAL WARMING. They are perfect examples of Green Chemistry and Sustainable Development.

For information on Fly Ash-based geopolymer cements go to European Research Project GEOASH. For updated very recent detailed information, read Chapters 12, 24, 25 in Geopolymer Chemistry & Applications; you may also download previous papers in the Library .

Rock-based geopolymer cements are ideal for environmental applications, such as the permanent encapsulation of radioactive and other hazardous wastes, toxic metals, as well as sealants, capping, barriers, and other structures necessary for remedying toxic waste containment sites (see our European Research Project GEOCISTEM and the GEOPOLYTECH process). See also in the Library .

Rock-based geopolymer cements and concretes for building and repairing infrastructure have very high early strength, their setting times can be entirely controlled, and they remain intact for a very long time without the need for repair. See in Davidovits’ book, Geopolymer Chemistry & Applications, the Chapters 9, 10, 24 and 25. The strength of geopolymeric rock-based geopolymer concrete is such that a heavy Boeing or Airbus can land on a runway freshly patched with geopolymeric rock-based geopolymer concrete only four hours after patching has been completed. The discovery of this new cement was awarded with a Gold Ribbon by the American National Association for Science, Technology and Society (NASTS) in 1994 (Library paper #3 NASTS award ).

Geopolymer specialty

Geopolymer ceramic

Several decades ago, ceramicists tried to manufacture ceramic tiles at temperatures lower than 450°C, without firing. Geopolymer science masters the transformation of kaolinite, the major component of ceramic clays, into geopolymers of the poly(sialate) and poly(sialate-siloxo) types. Application of this chemistry yielded several technological breakthroughs pertaining to LTGS, Low-Temperature-Geopolymeric-Setting and geopolymerized modern ceramic processing. See in Chapter 23 of Davidovits’ book Geopolymer Chemistry & Applications .

Geopolymer high-tech/ fiber reinforced composite

Geopolymer composites have three main properties that make them superior to ceramic-matrix composites, plastics, and organic composite materials.

First:
Geopolymers are very easy to make, as they handle easily and do not require high heat.
Second:
Geopolymeric composites have a higher heat tolerance than organic composites. Tests conducted on Geopolymer carbon-composites showed that they will not burn at all, no matter how many times ignition might be attempted.
Third:
The mechanical properties of Geopolymer composites are as good as those of organic composites. In addition, Geopolymers resist all organic solvents (and are only affected by strong hydrochloric acid).

Before the discovery of geopolymerization, these three critical properties had not been incorporated into any one material. More information are available in applications called GEO-COMPOSITE and GEO-STRUCTURE and in Davidovits’ book Geopolymer Chemistry & Applications , Chapter 21.

An Example of the Development of Geopolymeric Composites and Cements That Improves Air Travel Safety and Airport Efficiency*

The Chapters of the book GEOPOLYMER Chemistry & Applications dedicated to these applications are referred to in italic.

A jet is preparing for takeoff from a runway in New York as a crew begins placing a section of geopolymer concrete (Chapters 24, 25) on a Los Angeles runway. The plane is equipped with a fire-resistant geopolymer-encased electronic flight recorder. The jet’s cabin has also been rendered fireproof with sandwich panels of carbon/Geopolymite® composites (Chapter 21) and geopolymer foam insulating boards (Chapter 22). The jet is also equipped with a highly advanced fireproof air filter. Several structural components of the jet, made with an advanced SPF Al superplastic aluminum alloy, have been manufactured at 550°C using compression ceramic tools made of geopolymer materials (Chapter 20).

When the plane is ready to land in Los Angeles, the runway repaired with Pyrament® concrete will be ready for it.

The Ecologist

As part of a major Technology Strategy Board (UK) funded project Imperial College London, in collaboration with Tetronics Ltd, has completed research on the production of geopolymers from DC plasma treated air pollution control (APC) residues. APC residues are a hazardous waste produced from the cleaning of gaseous emissions at Energy from Waste (EfW) facilities processing Municipal Solid Waste (MSW). APC residues have been blended with glass-forming additives to facilitate the formation of a vitreous product and treated using DC plasma technology. This produces a calcium aluminosilicate glass (APC glass) which was used as the raw material for the production of geopolymers. Work has shown that high strength geopolymers can be formed. The broad particle size distribution of the milled APC glass used in the experiments resulted in a microstructure that contains un-reacted APC glass particles included within a geopolymer binder phase. Due to the high calcium content of the APC glass the binder phase formed a three dimensional geopolymeric network that contains hydration products including C-S-H gel which contribute to the excellent final mechanical properties of the material. The research demonstrates, for the first time, that glass derived from DC plasma treatment of APC residues can be used to form high strength geopolymer-glass composites, and these have potential to be used in a range of applications. DC plasma process is an integrated sustainable solution for APC residues management, fulfilling the aim of the EU waste policy as it is a recycling/recovery option higher in waste hierarchy than the existing management options. The use of APC residue plasma derived glass in the production of geopolymers provides a reuse option that promotes resource efficiency and carbon footprint minimisation. More information can be found in the recent publication in the Journal of Hazardous Materials:

To watch the keynote video, go to Mass Production of Geopolymer Cements

one can read the following comment to the article that favored Geopolymer concrete:

“Not really all that amazing.
The CO₂ emissions from cement production (from calcination, ie, not from the fuel used) are all reabsorbed by the cement over the decades that it stands there as a building.”

This is a fairy tale. I posted following comment:

“Tim Worstall is wrong for at least three reasons.
1) Yes, it is known that Portland cement concrete reabsorbs CO₂, but this phenomena occurs only on the surface of the concrete blocks (maximum 1-2 centimeters deep).
2) This CO₂ absorption happens very slowly and it would take centuries to recarbonate concrete blocks. There are historical remains of lime-based concrete that still contain uncarbonated lime after more than 1000 years. This means that the kinetic of CO₂ emission during Portland manufacture is 1000 times faster than its reabsorption.
3) Concrete specialists avoid CO₂ absorption because it is deleterious to Portland cement concrete. Indeed, Carbonation lowers the pH of the concrete and by so doing weakens the steel bars that become susceptible to rust (main cause of concrete degradation).”
