Professor Joseph Davidovits is known by the scientific community for being the inventor of geopolymer science. The general public recognizes his works on archaeological science and his discoveries regarding building the pyramids in Egypt. He posited that the blocks of the Great Pyramid are not carved stone but mostly a form of limestone concrete or man-made stone. This odd theory is officially endorsed by several renown materials scientists. He holds the French « Ordre National du Mérite », is the author and co-author of numerous scientific papers and conferences reports, and holds more than fifty patents.
In 1958, he obtained a chemical-engineer degree (Ingénieur-chimiste) at the Ecole Nationale Supérieure de Chimie, Rennes, France followed by a Dr.rer.nat in organic polymer chemistry at the University of Mainz, Germany in 1960. Between 1962 to 1972, he researched in organic polymers for the textile industry in France. In 1964, he received the Annual Award from the French Textile Chemical Society for his work on linear organic polymers. Although his chemistry background had focused on organic polymer chemistry, in the aftermath of various catastrophic fires in France between 1970-72, which involved common organic plastic, he decided to carry out research into new heat-resistant and fire-resistant mineral polymers. In 1972, he founded he French private research company Cordi (SA) (called later Cordi-Géopolymère SARL), a family owned company. All publications related to the research from 1972 to 1979 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 scientific organization Geopolymer Institute. In 1983, he was appointed Professor of Chemistry at Barry University, Miami, Florida, and there he founded the Institute for Applied Archaeological Sciences (IAPAS) to study worthwhile ancient technologies and advance the clarity of ancient history. Between 1983 and 1989, in collaboration with Lone Star Industries of the United States, he developed the geopolymer cement called PYRAMENT and its associated cement blends. For this breakthrough in cement technology, the National Association for Science, Technology and Society (NASTS) and the Federation of Materials Societies, USA, gave him the Gold Ribbon Award in 1994, jointly with James Sawyer from Lone Star Industries. He was an active member of several scientific societies including American Chemical Society, American Ceramic Society, American Concrete Institute, New York Academy of Sciences and International Association of Egyptologists. In 2008, he started publishing the reference text book « Geopolymer Chemistry and Applications » that he is still updating on a regular basis (4th edition is released in 2015). In 2015, he is launching the first « Journal on Geopolymer Science » with the publisher Elsevier.
He is the President of the Geopolymer Institute and Chair of the annual conference Geopolymer Camp, Saint-Quentin, France. This is a workshop-conference aimed at gathering academic as well as industrial scientists willing to meet, share and learn about geopolymers at large. Professor Davidovits’ research is applications driven and his main undertaking is to ensure the industrial success of this new chemistry in the following fields: fire resistant materials, decorative stone artifacts, thermal insulation, low-tech building materials, low energy ceramic tiles, refractory items, thermal shock refractories, foundry applications, eco-cements and concretes, composites for infrastructures repair and strengthening, high-tech composites for aircraft interior and automobile, high-tech resin systems, radioactive and toxic waste containment, arts and decoration, cultural heritage, archaeology and history of sciences.

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.

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.
