Geopolymer Institute

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 Library, [...]

Curtin Research Report on Fly Ash-Based Geopolymer Concrete
Reinforced beams and columns
by Djwantoro Hardjito and B.Vijaya Rangan
Research Report GC 3 (120 pages) (mar. 2006)
Faculty of Engineering, Curtin University of Technology
Perth, Australia
This Research Report describes the behaviour and strength of reinforced low-calcium fly ash-based geopolymer concrete structural beams and columns. Earlier, Research Reports GC1 and GC2 covered [...]

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 Thanks to these historical references, [...]

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, at [...]

X-rays diffraction spectra of hardened geopolymeric materials (resins and cements) do not supply accurate information (amorphous structure). High-resolution MAS-NMR (Nuclear Magnetic Resonance) spectroscopy of 29Si and 27Al is a very powerful tool that provides useful structural data.
For more updated information, see in Davidovits’ book, Geopolymer Chemistry & Applications, the Chapter 4. You may also [...]

The atomic ratio Si:Al in the poly(sialate) structure determines the properties and application fields. A low ratio Si:Al (1,2,3) initiates a 3D-Network that is very rigid. A high ratio Si:Al, higher than 15, provides polymeric character to the geopolymeric material. One third of Davidovits’ book, GEOPOLYMER Chemistry & Applications, is dedicated to applications. See the [...]

Prof. Joseph Davidovits presents the road map for the next couple of years on geopolymer science innovation and research, at the 2nd International Congress on Ceramics, Verona, Italy, July 4th, 2008. Watch the video on YouTube.
There is a great need for innovation and therefore further research must be carried out. We have listed below [...]

30 Years of Successes and Failures
in Geopolymer Applications.
Market Trends and Potential Breakthroughs.
by Joseph Davidovits
Invited Paper, Geopolymer 2002 International Conference, October 28-29, Melbourne, Australia
The presentation included 30 slides describing following geopolymer applications developed since 1972 in France, Europe and USA. The Geopolymer chemistry concept was invented in 1979 with the creation of a non-for profit scientific [...]
