Joseph (Joseph) Davidovich is a famous scientist chemist, a specialist in the field of low-temperature synthesis of minerals. In 1972, he founded a private research company CORDI in France, and in 1979 - Institute of geopolymer (Geopolymer Institute), also in France , p.68. He founded a new branch of applied chemistry, called geopolymerization. As a result, it geopolymerization create concrete that is virtually indistinguishable from some natural rock. I. Davidovich wrote: "Any rock can be used in powdered form and is obtained from it geopolymer concrete is virtually indistinguishable from natural stone. Geologists unfamiliar with the capabilities geopolymerization ... take geopolymer concrete for natural stone ... Neither high temperatures nor high pressures are not required for the production of the artificial stone. Geopolymer concrete sets quickly at room temperature and becomes a beautiful artificial stone ", p.69. Thus, according to J. Davidovich opened them geopolymer concrete is not required for its production or high-temperature treatment, no modern technology , p.69.
