We had a strong attendance (ca. 200 registered participants split between the two daily sessions). The videos are genuine tools for those of you who want to learn and increase their knowledge in Geopolymer Science and Technology. We have to learn how to use this new internet tool, improve the connection and take the best advantage of it. I am planning several other webinars on specific topics in the near future.

We would like to share with you a piece of the website’s little story. You see, in the picture below, a copy of 4 home pages, illustrating the 4 versions in which the website evolved. And still from the beginning, the website is developed, coded, designed and maintained by Ralph Davidovits.

The first version was officially launched on January 14th, 1996 at the ICCI’96 congress in Tucson, USA, during a presentation of Prof. Joseph Davidovits. It was hosted at our local university (INSSET, part of the university of Picardie, in France) on an Apple PowerMac 6100 and a 64kb internet line. There were around 25 pages, and already 11 papers free to download in the library. During the first year, we get around 10 to 15 visitors per day, but we expected this audience in one month! From this moment on, we really measures the true demand on geopolymers, and the necessity to develop something better for the community.

The second version was released a year after. We asked a friend to do some design works in order to offer a more attractive website. We got a new logo for the Geopolymer Institute and a new layout. In one year, 1500 papers were downloaded from the library. In addition, it was acclaimed as one of the best scientific website in the world by different sources! In 1998, the local university got a 128kb internet line and hosted our website on a Linux server.

The third version was launched in year 2000, with a professional hosting company and a real domain name (geopolymer.org). We used all the technology of that time, and was managed in a more professional way, with 270 pages, 30000 visitors per year, and we translated some part in French. Until then, everything was in English.

The fourth and last version was released on march 2006, and is using the cutting edge internet technology in a dynamic website, and sporting a new logo for the Geopolymer Institute. It took 3 months to develop it. You can subscribe to its RSS feed and even read it on you mobile phone or PDA! Our new website is ready to hold 1000 visitors a day (it happened in early December 2006), bigger downloads of bigger files and also videos, yet 130000 files have been downloaded from the library.
We hope to keep this one for the next 5 years.

Did you notice? This website is really free, no ads, no cookies, no proprietary files, because we care of your privacy, the ease of use, the access to all users (not a majority), even impaired ones, thanks to our respects to open standards and free softwares.

And again, thank you for your support and your enthusiasm in the geopolymer science!

The Geopolymer Institute Web site is the reference in this topic and has a big success. It is an excellent promotion tool for this new science, worldwide. This is reflected by the high number of downloadings for all scientific papers available here (see on this page the Statistics of downloadings).

That is why, we invite students (in Master and Doctorate) and researchers who want to take advantage of our popularity to benefit a web hosting of their most outstanding published papers or their most remarkable thesis (in English, or in French with a summary in English). You will have access to an audience much bigger than the original publication in a scientific journal or university libraries.

The institute does not publish articles but proposes to put on the internet already published scientific papers or thesis, provided you have the right to do it. Please, contact us to take advantage of this opportunity.

The second paper dealt with the famous Herodotus text; see the paper IXth Egyptology Congress, Grenoble, 2004: Herodotus and Pyramid construction (“Construction des pyramides d’après Herodote”), in French.

From 2001, we have conducted some important research on the development, manufacture, behaviour, and applications of Low-Calcium Fly Ash-Based Geopolymer Concrete. This concrete uses no Portland cement; instead, we use the low-calcium fly ash from a local coal burning power station as a source material to make the binder necessary to manufacture concrete. Concrete usage around the globe is second only to water. An important ingredient in the conventional concrete is the Portland cement. The production of one ton of cement emits approximately one ton of carbon dioxide to the atmosphere. Moreover, cement production is not only highly energy-intensive, next to steel and aluminium, but also consumes significant amount of natural resources. In order to meet infrastructure developments, the usage of concrete is on the increase. Do we build additional cement plants to meet this increase in demand for concrete, or find alternative binders to make concrete?

In this work, low-calcium (ASTM Class F) fly ash-based geopolymer is used as the binder, instead of Portland or other hydraulic cement paste, to produce concrete. The fly ash-based geopolymer paste binds the loose coarse aggregates, fine aggregates and other unreacted materials together to form the geopolymer concrete, with or without the presence of admixtures. The manufacture of geopolymer concrete is carried out using the usual concrete technology methods. As in the case of OPC concrete, the aggregates occupy about 75-80 % by mass, in geopolymer concrete. The silicon and the aluminium in the low-calcium (ASTM Class F) fly ash react with an alkaline liquid that is a combination of sodium silicate and sodium hydroxide solutions to form the geopolymer paste that binds the aggregates and other unreacted materials.

should you have any questions on these papers, please don’t hesitate to tell me via email.

The interest in this chemistry is becoming big.
