Geopolymer Institute

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 [...]

Left: hardening of Portland cement (P.C.) through simple hydration of Calcium Silicate into Calcium Di-Silicate hydrate and lime Ca(OH)2.
Right: hardening (setting) of Geopolymer resin (GP) through poly-condensation of Potassium Oligo-(sialate-siloxo) into Potassium Poly(sialate-siloxo) cross linked network.

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 Vimeo.
There is a great need for innovation and therefore further research must be carried out. We have listed below the [...]

Environmentally Driven Geopolymer Cement Applications.
by Joseph Davidovits
Invited Paper, Geopolymer 2002 International Conference, October 28-29, Melbourne, Australia
Environmentally driven geopolymer applications are based on the implementation of (K,Ca)-Poly(sialate-siloxo) / (K,Ca)-Poly(sialate-disiloxo) cements. In industrialized countries (Western countries) emphasis is put on toxic waste (heavy metals) and radioactive waste safe containment. On the opposite, in emerging countries, the applications [...]

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 [...]

PROPERTIES OF GEOPOLYMER CEMENTS
by Joseph Davidovits
published in the Proceedings, pp. 131-149
Geopolymer cement, high-alkali (K-Ca)-Poly(sialate-siloxo) cement, results from an inorganic polycondensation reaction, a so-called geopolymerisation yielding three dimensional zeolitic frameworks. High-tech Geopolymer K-Poly(sialate-siloxo) binders, whether used pure, with fillers or reinforced, are already finding applications in all [...]

Toxic metals immobilisation
PART I. Theory and Applications
by
J.G.S. van Jaarsveld, J.S.J.van Deventer and L. Lorenzen
published in : Minerals Engineering, Vol. 10, no. 7, pp. 659-669 (1996)
During the last decade geopolymerisation has emerged as a possible technological solution for the effective stabilisation and immobilisation of toxic materials. Despite the fact that this technology is based on a [...]

Global Warming Impact on the Cement and Aggregates Industry
by Joseph Davidovits
published in World Resource Review, Vol.6 (2), pp. 263-278 (1994)
CO2 related energy taxes are focusing essentially on fuel consumption, not on actual CO2 emission measured at the chimneys. Ordinary Portland cement, used in the aggregates industries, results from the [...]
