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 [...]
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 level of [...]
GEOpolymeric Cements for Innocuous
Stabilisation of Toxic EleMents
Geosynthesis 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.
The project seek to manufacture economical geopolymeric [...]
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 [...]
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 stabilization, solidifying and storing [...]
Geopolymeric cements are ideal for environmental applications, such as the permanent encapsulation of radioactive and other hazardous wastes, toxic metals, as well as sealants, capping, barriers, and other structures necessary for remedying toxic waste containment sites (see our Research Project GEOCISTEM and the GEOPOLYTECH® process). In the Library, three papers are dealing with this topic, [...]
