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 their properties. Geopolymers [...]

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 already finding applications in all [...]

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 achieved by the use [...]

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 technology is based on a [...]

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 aggregates industries, results from the [...]

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 and non-combustible plastic materials became [...]

Geopolymer-Carbon Composite for Repair and Rehabilitation
of Reinforced Concrete Beams
by

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 further compares GEOPOLYMER/CARBON composite to organic matrix composites [...]
