Cements, Concretes, Toxic Wastes, Global Warming
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 [...]
Innovation and further researches
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 [...]

#16: Environmentally Driven Geopolymer Cement Applications
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 [...]
#10: From ancient concretes to Geopolymers
Arts et Métiers Magazine N°180, Sept. 1993: From ancient concretes to geopolymer “Des bétons antiques au géopolymère” ( in English, en Français ) This paper has been adapted from an article written for the general audience by two independent French journalists. It outlines the story of geopolymer and his inventor Prof. Joseph Davidovits . Click [...]
#8: Alkaline Cements and Concretes, Properties of Geopolymer cements
1rst International Conference on Alkaline Cements and Concretes KIEV Ukraine, 1994 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 [...]
#7: Concretes for Nuclear Waste and Uranium Waste Containment
Recent Progresses in Concretes for Nuclear Waste and Uranium Waste Containment by Joseph Davidovits published in Concrete International, Vol.16 (12), pp. 53-58 (1994) The main objective in the management of nuclear and uranium radioactive wastes is to protect current and future generations from unacceptable exposure to radiation from man-made materials. This task can best be [...]
