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 natural [...]

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 [...]

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 geologist [...]

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 [...]

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 [...]

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 [...]

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 compressed to [...]

Geopolymeric Cross-Linking (LTGS) and Building Materials
Geopolymer’88 Proceedings, Vol. 1, pp. 79-88
“Réticulation Géopolymérique et Matériaux de Construction”
In English:
After a concise presentation of the chemical principles governing the LTGS geopolymeric cross-linking with the main mineralogical components of soils, earths and clays, the authors present their experiments for a rational use of lateritic materials. Several tests were carried [...]
