US Air Force satisfied with geopolymer developments

May 29, 2006 | No Comments

Report from the Air Force Research Laboratory on geopolymer research and developments report project number 9. AFRL is funding and conducting cutting-edge geopolymer research. Both intramural and extramural research has led to the development of new ceramics materials that possess superior properties, leading to more cost-effective choices in the design of future Air Force (AF) [...]

Potential utilization for geopolymer composites materials

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 [...]

Chemical Structure and Applications

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, [...]
