#10: From ancient concretes to Geopolymers
Arts et Métiers Magazine N°180, Sept. 1993: From ancient concretes to geopolymer “Des bétons antiques au géopolymère” ( in English, en Français ) This paper has been adapted from an article written for the general audience by two independent French journalists. It outlines the story of geopolymer and his inventor Prof. Joseph Davidovits . Click [...]
#9: Ultra-High Temperature Tooling Material for the Manufacture of Advanced Composites
Ultra-High Temperature Tooling Material for the Manufacture of Advanced Composites SAMPE 1991, 36, vol. 2, pp 1939-1949: Geopolymers of the Poly(sialate-disiloxo) type (- Si-O-Al-Si-O-Si-O -), very-low viscosity inorganic resins, harden like thermosetting organic resins, but have use-temperature range up to 1000°C (1830°F). High-temperature techniques are no longer necessary to obtain materials which are ceramic-like in [...]
#8: Alkaline Cements and Concretes, Properties of Geopolymer cements
1rst International Conference on Alkaline Cements and Concretes KIEV Ukraine, 1994 PROPERTIES OF GEOPOLYMER CEMENTS by Joseph Davidovits published in the Proceedings, pp. 131-149 Geopolymer cement, high-alkali (K-Ca)-Poly(sialate-siloxo) cement, results from an inorganic polycondensation reaction, a so-called geopolymerisation yielding three dimensional zeolitic frameworks. High-tech Geopolymer K-Poly(sialate-siloxo) binders, whether used pure, with fillers or reinforced, are [...]
#7: Concretes for Nuclear Waste and Uranium Waste Containment
Recent Progresses in Concretes for Nuclear Waste and Uranium Waste Containment by Joseph Davidovits published in Concrete International, Vol.16 (12), pp. 53-58 (1994) The main objective in the management of nuclear and uranium radioactive wastes is to protect current and future generations from unacceptable exposure to radiation from man-made materials. This task can best be [...]
#6: Toxic metals immobilisation
Toxic metals immobilisation PART I. Theory and Applications by J.G.S. van Jaarsveld, J.S.J.van Deventer and L. Lorenzen published in : Minerals Engineering, Vol. 10, no. 7, pp. 659-669 (1996) During the last decade geopolymerisation has emerged as a possible technological solution for the effective stabilisation and immobilisation of toxic materials. Despite the fact that this [...]
#5: Global Warming Impact on the Cement and Aggregates Industry
5th International Global Warming Conference San Francisco, 1994 Global Warming Impact on the Cement and Aggregates Industry by Joseph Davidovits published in World Resource Review, Vol.6 (2), pp. 263-278 (1994) CO2 related energy taxes are focusing essentially on fuel consumption, not on actual CO2 emission measured at the chimneys. Ordinary Portland cement, used in the [...]
#4: Fire response of geopolymer structural composites
1rst International Conference on Composites in Infrastructure Tuscon, Arizona, Jan. 1996 Fire response of geopolymer structural composites by Richard E. Lyon, Usman Sorathia, P.N. Balaguru , Andrew Foden, Joseph Davidovits and Michel Davidovics published in the Proceedings of ICCI’96, pp. 972-981; see also the paper on pages166-177 The fire response of a potassium aluminosilicate matrix [...]

NASTS award 1994 Presentation at the national “Real Advances in Materials” Symposium, Washington DC, Sept. 26,1994 GEOPOLYMERS: Inorganic polymeric new materials by Joseph Davidovits published in Journal of Materials Education, Vol. 16 (2,3), pp. 91-138 (1994) In the aftermath of various catastrophic fires in France between 1970-73, which involved common organic plastic, research on non-flammable [...]
#2: Reinforced Concrete Beams
Geopolymer-Carbon Composite for Repair and Rehabilitation of Reinforced Concrete Beams by P. Balaguru, Stephen Kurtz, and Jon Rudolph, Rutgers The State University of New Jersey, Piscataway, NJ -08855-0909, U.S.A. This report presents the results of an experimental investigation of the behavior of reinforced concrete beams strengthened with carbon fiber fabrics and geopolymer. The primary objective [...]
#1: Fire resistant aluminosilicate composites
Richard E. Lyon, P.N. Balaguru, Andrew Foden, Usman Sorathia, Michel Davidovics and Joseph Davidovits. published in the journal “Fire and Materials”, USA, 1996 This paper presents the latest results on the properties of GEOPOLYMER/CARBON composite, namely: * viscosity, chemical reactivity, differential scanning calorimetry, thermogravimetric analyses, mechanical properties (inplane shear, interlaminar shear, warp tensile, flexure). It [...]
