Giving Survivors More Time to Escape
A carbon-epoxy aerospace composite (left) is burning while a carbon-geopolymer composite (right) still resists a 1200°C fire.
When a plane crash-lands and catches fire, half the people who survive the impact may not get out in time. That is because the plastics in the cabin—the seat cushions, carpeting, walls [...]
The atomic ratio Si:Al in the poly(sialate) structure determines the properties and application fields. A low ratio Si:Al (1,2,3) initiates a 3D-Network that is very rigid. A high ratio Si:Al, higher than 15, provides polymeric character to the geopolymeric material. One third of Davidovits’ book, GEOPOLYMER Chemistry & Applications, is dedicated to applications. See the [...]
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, [...]
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 of a non-for profit scientific [...]

This paper presents the latest results on the properties of GEOPOLYMER/CARBON composite, namely: * viscosity,
chemical reactivity,
differential scanning calorimetry,
thermogravimetric analyses,
mechanical properties (inplane shear, interlaminar shear, warp tensile, flexure).
It further compares GEOPOLYMER/CARBON composite to organic matrix composites [...]
