Breakthrough at Imperial College London
Geopolymers using glass produced from DC plasma treatment of air pollution control (APC) residues As part of a major Technology Strategy Board (UK) funded project Imperial College London, in collaboration with Tetronics Ltd, has completed research on the production of geopolymers from DC plasma treated air pollution control (APC) residues. APC residues are a hazardous [...]

Geopolymer Training courses start April 01, 2008
The Geopolymer Institute is introducing a series of training courses on Geopolymer Chemistry, Geopolymer Science and related Applications. The 2-day and 3-day courses will be held at the Geopolymer Institute, Saint-Quentin, France (one and half hours drive North of Paris), with low-rates Hotels in the vicinity. The first series of courses start on April 01. [...]
First Book on Geopolymers!
Professor Joseph Davidovits is proud to announce the release of his book entitled: GEOPOLYMER CHEMISTRY AND APPLICATIONS with ca. 590 pages and 26 Chapters. The photo shows the first printing for proof-reading. We expect to get the first exemplars printed for the end of February 2008. The first edition of the book will be sold [...]
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 [...]
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 [...]
Heavy metals immobilisation
Heavy metals immobilization follows two steps: First: dissolution, solubilization of the heavy metal, due to high pH (no precipitation as hydroxides); Second: charge balancing role like any cations (Na or K). Immobilization is not encapsulation, but regular geopolymerization. These steps are disclosed in French in the published International patent application WO 89/02766, titled “Method for [...]
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 [...]
