Geopolymer Revolution on the Move
BASF, the world Chemical Company is strongly promoting geopolymer technology. In an older post dated of 24 March, 2011, we introduced the geopolymer grout PCI-GEOFUG (go to BASF). Meanwhile, the company presents it at various international fairs and expositions, starting from Germany over UK, and presently in Paris, at BATIMAT (8 Nov., 2011). It is [...]
PYRAMENT cement good for heavy traffic after 25 years
Message: Professor Joseph Davidovits, I recently purchased your latest book and have read a number of your papers and learned that I have you to thank for Pyrament Cement. My first experience using Pyrament was about 23 years ago when we were the first to use it to replace damaged concrete on runways and taxiways [...]
Are Pyramids Made Out of Concrete? (1)
The pyramids stones are man-made (synthetic, artificial) Cast in molds The Pyramids at Giza have more than 5 million blocks of limestone, until now believed to be CARVED stones, new evidences shows they were CAST with agglomerated limestone concrete. The website reveals how Ancient Egyptians built the pyramids using man-made stones, which look exactly like [...]
Pyramids (2) The evidences
The scientific proofs The “Lauer” sample under the optical microscope. This photo shows a sample of the casing from the ascending passage of Kheops great pyramid, given by the French egyptologist Jean-Philippe Lauer in 1982 to J. Davidovits. Now, the cross section is characterised by the presence of organic fibers and air bubbles that do [...]
Pyramids (3) The formula, the invention of stone
Why do geologists see nothing? This is due to the geological glue, which, though artificial, is seen by the geologists either as an impurity, and therefore useless to study, or as a natural binder. At best, the analysis tools and the working methods of geologists consider the glue as a perfectly natural “micritic binder”. A [...]
Papers dedicated to archaeology in Geopolymer Proceedings
Brief summary of the papers dedicated to archaeology and published in the Geopolymer Proceedings : Geopolymer 2005 and Geeopolymer ‘99 Geopolymer 2005 Synthetic stone in Ancient Egypt and Mesopotamia manufacture of synthetic lava and synthetic basalt and decipherment of the C-14 Irtysen Stele (2000 B.C.)

Introduction: developments and applications in geopolymer
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 [...]
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 [...]
Archaeological Analogues (Roman Cements)
Long-Term Stability of Geopolymeric Materials The task LONGTERM in the GEOCISTEM project dealt with the better understanding of long-term durability. It is difficult to predict extended durability on the basis of operating experience, laboratory experimentation and prototype testing. Two thousand years are generally accepted as a sufficient amount of time to permit decay of fission [...]
LTGS Brick, low cost construction material
A low cost, easy to produce solution The geopolymer LTGS brick is an ideal construction technology for emerging countries, because it offers many characteristics that fulfils the population demands. This brick uses a very cheap material available in great quantity: lateritic clay earth. This special and abundant earth, mixed with a simple geopolymer binder is [...]
