Milestone paper IUPAC 1976, in the LIBRARY
Several geopolymer scientists asked me to make available for free download in the LIBRARY, my first paper presented at the IUPAC Symposium on Long-Term Properties of Polymers and Polymeric Materials. This symposium held in Stockholm, Sweden, Aug. 30 to Sept. 1, 1976, had a session Topic III dedicated to New Polymers of High-Stability. I had [...]
# 20 Milestone paper IUPAC 76
Full Paper of the communication presented at IUPAC Symposium on Long-Term Properties of Polymers and Polymeric Materials, Stockholm 1976, Topic III. Solid-Phase Synthesis of a Mineral Blockpolymer by Low Temperature Polycondensation of Alumino-Silicate Polymers: Na-poly(sialate) or Na-PS and Characteristics . Joseph DAVIDOVITS INTRODUCTION The work exposed here comes from an attempt to transfer our [...]
GEO-COMPOSITE: fire resistant matrix
Fire resistant matrix materials for use in aircraft composites and cabin interior applications The Federal Aviation Administration (F.A.A.), USA, has recently initiated a research program to develop low-cost, environmentally-friendly, fire resistant matrix materials for use in aircraft composites and cabin interior applications. The flammability requirement for new materials is that they withstand a 50 kW/m2 [...]

Ceramics, Binders and Composites
Geopolymeric binders, used either with rock aggregates to produce rock-concretes or with carbon fibers to produce non-flammable composites, have a variety of important industrial uses. The same geosynthesis that produces geopolymeric rock-cements is used industrially for making binders for advanced composite materials and ceramics. Updated research is presented in Davidovits’ book, Geopolymer Chemistry & Applications, [...]
