Materials for the Third Millennium
Think Geopolymer and Geosynthesis!

The last few years have seen spectacular technological progress in the development of geosynthesis and geopolymeric applications.
New state-of-the-art materials designed with the help of geopolymerisation reactions are opening up new applications and procedures, and transforming ideas that have been taken for granted in inorganic and mineral chemistry.
Since the [...]

Since 1985, French and English nuclear power stations equipped theirs plants with air filters produced by Sofiltra-Camfil, a French company, in which joints and dust free sealants are made of geopolymer, providing a safety cover up to 500°C. Source: Sofiltra-Camfil patent

Geopolymer insure thermal protection of industrial buildings and facilities up to 1200°C. Hüls [...]

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 [...]

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 [...]

Geopolymer Composite Applications, Fireproof panels, Fireproof Decoration

The patented GEOPOLY-THERM technology is based on the use of geopolymer binders. The effects of fires aboard vessels have been demonstrated as a result of collision between ships and ferries during peace time, and by experiences of the British Navy in the Falkland Islands and the [...]

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 [...]

Geopolymer tremendously improves cement characteristics
For information on Fly Ash based Geopolymer Cements and Concretes

Ordinary cement, often called by its formal name of Portland cement, is a serious atmospheric pollutant. Studies have shown that one ton of carbon dioxide gas is released into [...]

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 [...]
