Geopolymer Institute

On January 14th, 2007, we celebrate the 11th anniversary of the Geopolymer Institute Website. It is the first time we share this event with you, dear visitors. You are reading the first source of geopolymer science and we thank you for making it a success.
We would like to share with you a piece of the [...]

The scientific magazine NATURE, vol. 444, 793 (14 december 2006) writes in his News about the recent analysis on pyramid stones:
Materials Science: Concrete evidence
J. Am. Ceram. Soc. 89, 3788–3796 (2006)
Some of the massive blocks making up the great pyramids of Giza in Egypt (pictured) are not limestone, but a synthetic mix like concrete, argue materials [...]

On November 30, the Journal of the American Ceramic Society has released a very important scientific research carried out on the pyramid stones, which confirms the theory developed by Professor Joseph Davidovits on agglomerated (artificial) limestone concrete (ancient geopolymer).
The references of this paper are :

Dr. R. Lyon from Federal Aviation Administration, USA and Dr. P. Balaguru from Rutgers University, NJ, USA, have published a new paper involving the use of a geopolymer coating on light balsa wood, for aircraft application. The title of the paper:
Use of Inorganic Polymer to Improve the Fire Response of Balsa Sandwich Structures

The geopolymer group at ANSTO (Dr. Dan S. Perera), Australian Nuclear Science and Technology Organisation, has released a paper on the geopolymer-kalsilite-leucite heat transformation. It is available for free download
Abstract
A geopolymer was prepared by dissolving metakaolinite in a solution of K2SiO3 and KOH and curing at 80°C for 24 h. It was progressively heated from [...]

Geopolymer laminate has been used by NASA in the manufacture of sophisticated mirrors : Advanced Processing of the Optical Surface on Large Lightweight Mirrors. The link to this application

In memoriam
It is with sorrow that I learned that my friend Georges Grimal died at the age of 98 years. The majority of our scientific colleagues, engineers and students, know at least one of his works of Art created with geopolymer. It is displayed on this site at the page Potential utilizations in Art and [...]

The oldest ceramic ever manufactured, the Venus of Dolni Vestonice, is displayed at the Anthropology Museum, at Brno, Czech Republic. The Venus of Dolni Vestonice was visited by Prof. Joseph Davidovits who writes:
” I still had for my eyes the image of the yellow limestone Venus displayed at the Vienna Museum, Austria, to be very [...]

Industrial Research has developed a process which will enable the fly ash waste material from burning coal at the Huntly Power Station to be used as a feedstock for making new geoploymer materials.
Geopolymers are being investigated as an alternative to traditional cement materials and for waste remediation of hazardous substances.
Previously the high calcium level of [...]

An international patent # WO 2004/026698 has been published on the making of fire-resistant containers. One of the inventors is Andrew Foden, former member of the geopolymer group at Rutgers University, Professor P. Balaguru, USA, and co-author of several papers on fire-resistant geopolymer composites.
