Joseph Davidovits

Extended biography

He is the author and co-author of approx. 130 publications including 50 patents issued and granted related to research dedicated to applied solid-state chemistry, geopolymeric materials.

1958: Diplome d’Ingénieur-Chimiste, Ecole Nationale Supérieure de Chimie, Rennes, France

1960: Dr. rer. nat in macromolecular chemistry, University of Mainz, Germany.

From 1962 to 1972: 10 years dedicated to research and developments dealing with organic polymers, which resulted in 19 publications involving the chemistry of poly-urethane, textile synthetic fibers, biological membranes and collagen.

1964 Annual Award from the French Textile Chemical Society for works performed on linear organic polymers

In 1972, in the aftermath of various catastrophic fires in France in 1970 involving inflammable organic plastics, he decided to carry out research into new heat-resistant materials. Creation of the French private Research Company CORDI (SA) (called now CORDI-GÉOPOLYMÈRE SARL) (family owned company). From 1972 until 1979, all publications related to this 7 year long research on alumino-silicate solid-state chemistry are pertaining to the patent literature. The “Geopolymer” concept was created and published in 1979, together with the foundation of the non-profit organization GEOPOLYMER INSTITUTE. More than 50 publications are disclosing 20 years of research and developments carried out in Europe and in USA on the applications of geopolymeric solid-state chemistry, with major breakthroughs in high-tech composite materials, cement-technology and the containment of radioactive and other hazardous waste.

In 1983 he was appointed Adjunct Professor of Chemistry at Barry University, Miami, Florida, and there he founded the Institute for Applied Archaeological Sciences (IAPAS). The IAPAS is established to study worthwhile ancient technology and advance the clarity of ancient history. The main focus has been on researching ancient cements in order to understand their long-term durability and test their performance of their modern counterparts (the said geopolymeric binders) for toxic and radioactive wastes containment. More than 14 publications and various books including the ” Book of Stone ” ” The Pyramids: an Enigma Solved ” (New York 1988) are dealing with this topic related to archaeometry and archaeology.

From 1983 to 1989: with LONE STAR INDUSTRIES, Inc. , USA. Development of geopolymeric cement and blended cements (PYRAMENT).

In 1989 he was appointed Visiting Professor in Solid-State Chemistry, at Pennsylvania State University (Penn State), where he worked with the Materials Research Laboratory. There he began research dedicated to the problem of Global Climate Warming, about 7 to 10% of which is due to Carbon-dioxide emissions during the manufacture of Portland cement (the implementation of geopolymeric cements can significantly reduce this problem).

Since 1991, he has been on sabbatical leave from university teaching and devote himself to the projects listed below.

1994 Gold Ribbon Award from NASTS, for most significant real advances in Materials Research of the last decade, from the National Association for Science, Technology and Society (NASTS), and the Federation of Materials Societies. The award was presented on September 26, 1994, at the National Press Club, Washington DC.

Past decade and Presently

  • President of the GEOPOLYMER INSTITUTE, France, a non-profit scientific society, dedicated to scientific research on ancient technologies (archaeology) and modern geopolymer technologies with international institutions.
  • Board of CORDI-GÉOPOLYMÈRE SARL, France, family owned holding company, dedicated to promoting new business opportunities with geopolymer technologies (composites for aeronautic, automobile, nuclear power plants, industries, cements, concretes, waste management, etc..), patents and trade marks.
  • Working on archaeology: writing books, Ils ont bâti les pyramides (Paris, 2002), La Nouvelle Histoire des Pyramides (Paris, 2004), La Bible avait raison (Paris, 2005 Vol. 1, 2006 Vol. 2) ; participating to TV documentaries, the Ari-Kat Saga (2004) produced by Relevant-Television
  • Principal Coordonator of the European industrial research program GEOCISTEM, funded by the European Union (BRITE-EURAM program, 1994-1997), dedicated to the industrial implementation of his new cements for the containment of hazardous and radioactive wastes and the rehabilitation of severely polluted mining and chemical sites, in Eastern Europe, and also to mitigate GLOBAL WARMING.
  • Working on the industrial research project GEO-COMPOSITES, funded by the Federal Aviation Administration, F.A.A. (in collaboration with Rutgers, State University of New Jersey). The project is dedicated to the development of fire-resistant geopolymeric composite materials for aircraft cabin.
  • Working on the industrial research project GEO-STRUCTURES, supported by several US institutions, which is dedicated to the development of geopolymeric composite materials for the repair and retrofit of infrastructures and buildings in earth-quake and hurricane prone areas.
  • Working on the industrial research project GEOCEMENT, supported by GEOCISTEM (see above) which is dedicated to the development of new cements for newly-industrialised countries, such as South America, South-East Asia, China, etc.. The new geopolymeric cements address the global greenhouse gas problem because they do not emit carbon dioxide. The project goal is the global conversion of the cement industry to geopolymeric materials that reduce global greenhouse gas emissions.
  • Appointed Honorary Professor of Xian University of Architecture (most famous Chinese institution in architecture and building technology): geopolymeric cements (project GEOCEMENT see above), archaeology (Sept. 1999).
  • Former Consultant (expert) to the European Union Commission. Research Directorate at Brussels for the key-action “Cultural Heritage”.
  • Scientific Consultant to the European research project GEOASH, funded by the European Union (RFCS COAL RTD PROGRAMME, RFC-CR-04005, 2005-2007) “Understanding and mastering coal fired ashes geopolymerization process in order to turn potential into profit”.
  • Chairman of the GEOPOLYMER 2005 WORLD CONGRESS.
