Joseph Davidovits

from Wikipedia, the free encyclopedia

Joseph Davidovits (born March 23, 1935 ) is a French chemist.

In 1958 he became a chemist at the École Nationale Supérieure de Chimie in Rennes . In 1960 he was awarded a Dr. rer. nat. is doing his doctorate with a dissertation on macromolecular chemistry.

1962–72 he researched and developed organic polymers . In 1964 he received the Annual Award from the French chemical textile industry.

In 1972, after a catastrophic fire in France in 1970 (fire in the Cinq-Sept dance hall in Saint Laurant-du-Pont?) With supposedly incombustible organic plastics, he began researching new heat-resistant materials and founded the private research company CORDI. He took up the work of Victor Dmitrievich Glukhovsky from the Kiev Institute of Civil Engineering from the 1950s again. In 1979 he published his concept of geopolymers and founded the Géopolymère Institute in Saint-Quentin .

1983-91 he was a professor at Barry University in Miami and at Pennsylvania State University . Here he founded the Institute for Applied Archaeological Sciences (IAPAS). From 1988–1999 he worked with the Institut de recherche sur les geopolymères et leurs applications at the Technical University of Compiègne .

In the early 1990s, the Wismut company planned to embed nuclear waste on a molecular level in geopolymer cement, but this failed because of the costs.

Theses on building pyramids

Davidovits advocates the thesis that the stone blocks used to build the pyramids of Giza are not made of natural stone, but were made of sodium-activated aluminum silicate.
This thesis is regularly taken up by some media, but strictly rejected by Egyptology .
