Cutting-Edge analysis proves Davidovits’ Pyramid theory
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 : Barsoum, M. W., Ganguly, A. & Hug, G. (2006), [...]
Paper on geopolymer-kalsilite-leucite transformation
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 [...]

Fly ash waste material as a geopolymer feedstock
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 [...]
EM image of vitrified geopolymer
The geopolymer group at University of Illinois, Prof. W. Kriven, participated to the Center for Microanalysis of Materials (CMM) image contest with an image titled: 10. Vitrification of 3SiO2:Al2O3:K2O:10H2O geopolymer gel by heating to 1600°C. Crystallization of the glass systems was dendritic as seen by in micrograph of the top surface. Jonathan Bell, Kriven group. [...]
US Air Force satisfied with geopolymer developments
Report from the Air Force Research Laboratory on geopolymer research and developments report project number 9. AFRL is funding and conducting cutting-edge geopolymer research. Both intramural and extramural research has led to the development of new ceramics materials that possess superior properties, leading to more cost-effective choices in the design of future Air Force (AF) [...]
Fly Ash based Geopolymer Concrete : 2 new reports from Curtin
The geopolymer group at Curtin University of Technology, Perth, Australia (Prof. V. Rangan) has released 2 new reports on Fly Ash Based Geopolymer Concrete. They may be downloaded from our Library. The first report: Report GC 2 is dealing with the long term properties. It has been included in the Technical Paper #17 in the [...]

Earlier, [...]
Introduction: Why an archaeology section at the Geopolymer Institute?
When all the logical conjectures have been set aside, the one that remains, as improbable as it may seem, is likely to be true. At the Geopolymer Institute we use archaeology as a data bank, to validate our discoveries (see the projects GEOCISTEM and Global Warming and the Geopolymer Proceedings ). Thanks to these historical [...]
The geopolymer chemistry was known during antiquity
Joseph Davidovits has found revolutionary ways of producing cements with plants saps, which could explain some of the mysteries associated with Pre-Columbian architectures. Preliminary results had been presented at two International Archaeometry Symposia. See in the library the paper #C Making Cements with Plant Extracts disclosing information dating back to 1981 and 1982. In 1979, [...]
