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 [...]

External repair and structural retrofit for aging infrastructure and aging buildings

Infrastructure in the United States such as bridges are degrading due to the corrosion of steel-reinforced concrete by salty water and deicing compounds. A relatively new and little known repair method for concrete and brick structures, consists of externally bonding flexible sheets [...]

Prof. Joseph Davidovits presents the road map for the next couple of years on geopolymer science innovation and research, at the 2nd International Congress on Ceramics, Verona, Italy, July 4th, 2008. Watch the video on YouTube.
There is a great need for innovation and therefore further research must be carried out. We have listed below [...]

Ultra-High Temperature Tooling Material
for the Manufacture of Advanced Composites
SAMPE 1991, 36, vol. 2, pp 1939-1949:
Geopolymers of the Poly(sialate-disiloxo) type (- Si-O-Al-Si-O-Si-O -), very-low viscosity inorganic resins, harden like thermosetting organic resins, but have use-temperature range up to 1000°C (1830°F). High-temperature techniques are no longer necessary to obtain materials which are ceramic-like in their properties. Geopolymers [...]

PROPERTIES OF GEOPOLYMER CEMENTS
by Joseph Davidovits
published in the Proceedings, pp. 131-149
Geopolymer cement, high-alkali (K-Ca)-Poly(sialate-siloxo) cement, results from an inorganic polycondensation reaction, a so-called geopolymerisation yielding three dimensional zeolitic frameworks. High-tech Geopolymer K-Poly(sialate-siloxo) binders, whether used pure, with fillers or reinforced, are already finding applications in all [...]
