Peter Duxson,Ana Fernández-Jiménez,John L. Provis,Grant C. Lukey,Ángel Palomo,J.S.J. van Deventer +5 more
TL;DR: A brief history and review of geopolymer technology is presented with the aim of introducing the technology and the vast categories of materials that may be synthesized by alkali activation of aluminosilicates as mentioned in this paper.
Journal ArticleDOI
The Role of Inorganic Polymer Technology in the Development of ‘Green Concrete’
TL;DR: In this paper, the potential position of and drivers for inorganic polymers (“geopolymers”) as an element of the push for a sustainable concrete industry are discussed.
Journal ArticleDOI
Carbon dioxide equivalent (CO2-e) emissions: A comparison between geopolymer and OPC cement concrete
TL;DR: In this article, the authors present the results of comprehensive carbon footprint estimates for both geopolymer and OPC concrete, including energy expending activities associated with mining and transport of raw materials, manufacturing and concrete construction.
Journal ArticleDOI
Advances in alternative cementitious binders
TL;DR: In this paper, four promising alternative binders available as alternatives to Portland cement are discussed, namely calcium aluminate cement, calcium sulfoaluminate cements, alkali-activated binders, and supersulfated cements.

New cements for the 21st century: The pursuit of an alternative to Portland cement
TL;DR: Aluminosilicate-based alkaline cements have been classified into five categories as discussed by the authors, and the key advances made in the understanding of synthetic gels are discussed, which ultimately finds hybrid cements to be technologically viable materials for contemporary construction.

The chemistry of cement and concrete
TL;DR: The chemistry of cement and concrete as discussed by the authors, The chemistry of concrete and its properties, and the relationship between concrete and cement, is a classic example of such an approach. But it is not suitable for outdoor use.
Emission Reduction of Greenhouse Gases from the Cement Industry
TL;DR: A wide range of options exist to reduce CO 2 emissions considerably as discussed by the authors, including calcination and combustion processes, from cement production, which accounts for about half of global carbon dioxide emissions.

Low-temperature synthesized aluminosilicate glasses
TL;DR: In this paper, the reaction below 100 °C of a dehydroxylated clay (metakaolinite: (Al2O3)(SiO2)2(H2O)005) suspended in an alkaline sodium silicate solution (Na2O),SiO 2)14(H 2O)x) leads to an amorphous glassy aluminosilicate, called in this work "low-temperature inorganic polymer glass" (LTIPG or IPG)

Gypsum of improved performance using blends with Portland cement and silica fume
TL;DR: In this paper, a study intended to develop a blend of gypsum and Portland cement, which would possess the advantages of both materials, such as early strength and enhanced workability, but would be free of the deleterious effect of ettringite.
