Geopolymer cement
There is often confusion between the meaning of the terms “cement” and “concrete”. A cement is a binder whereas concrete is the composite material resulting from the addition of cement to stone aggregates. Cement is sold to companies that make concrete. Geopolymer cement is often mixed up with alkali-activated slag developed since 1956 in Eastern [...]
Geopolymer cement for storage of toxic and radioactive wastes
GEOpolymeric Cements for Innocuous Stabilisation of Toxic EleMents Geosynthesis of Rock-based Geopolymer cements was the objective of the European multidisciplinary BriteEuram industrial research project GEOCISTEM. The project titled cost effective GEOpolymeric Cements for Innocuous Stabilization of Toxic EleMents, in short GEOCISTEM, started on Jan. 1994 and has been completed on June 1997. In J. Davidovits’ [...]
Hazardous and radioactive waste encapsulation treatment
GEOPOLYTECH: Toxic and Radioactive Waste Management The patented GEOPOLYTECH technology is based on the use of geopolymer binders. The GEOPOLYTECH technology could provide a safe and proven method for the encapsulation and long-term containment of toxic, hazardous, and radioactive sludges from decantation ponds and pasty wastes (filter cakes) from water treatment facilities. The technology is [...]
Potential utilizations in Art and Decoration
Georges Grimal, a French sculptor and painter, stated: Lighting has tremendous importance in sculpture. I call “dramatized sculpture” the idea of developing the sculpture and suitable lighting together. In these, the artist has incorporated light sources into the work itself, allowing the spectator to feel the key-points and sense the finesse in the half-shadow light [...]
#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 [...]
#15: 30 Years of Successes and Failures in Geopolymer 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 [...]
#12: Geopolymers: Inorganic Polymeric New Materials
J. Thermal Analysis (1991) GEOPOLYMERS: Inorganic Polymeric New Materials by Joseph Davidovits published in : Journal of Thermal Analysis, Vol. 37, 1633-1656 (1991) Spectacular technological progress has been made in the last few years through the development of new materials such as ‘geopolymers’, and new techniques, such as ‘sol-gel’. New state-of-the-art materials designed with the [...]

#9: Ultra-High Temperature Tooling Material for the Manufacture of Advanced Composites
Ultra-High Temperature Tooling Material for the Manufacture of Advanced Composites SAMPE 1991, 36, vol. 2, pp 1939-1949: Geopolymers of the Poly(sialate-disiloxo) type (- Si-O-Al-Si-O-Si-O -), very-low viscosity inorganic resins, harden like thermosetting organic resins, but have use-temperature range up to 1000°C (1830°F). High-temperature techniques are no longer necessary to obtain materials which are ceramic-like in [...]
#5: Global Warming Impact on the Cement and Aggregates Industry
5th International Global Warming Conference San Francisco, 1994 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 [...]
