Alkali-activated materials
TL;DR: In this paper, a brief discussion of the class of cementing materials known as "alkali-activated binders" is provided, which are identified to have potential for utilization as a key component of a sustainable future global construction materials industry.
Journal ArticleDOI
Advances in understanding alkali-activated materials
TL;DR: Alkali activation is a highly active and rapidly developing field of activity in the global research and development community as discussed by the authors, and commercial-scale deployment of alkali-activated cements and concretes is now proceeding rapidly in multiple nations.

Production of bricks from waste materials – A review
TL;DR: A state-of-the-art review of research on utilization of waste materials to produce bricks can be found in this article, which can be divided into three general categories based on the methods for producing bricks from waste materials: firing, cementing and geopolymerization.
Journal ArticleDOI
Clean production and properties of geopolymer concrete; A review
TL;DR: A comprehensive review of GeoPC material, its constituents, production techniques, curing regimes, properties and its potential applications in the construction industry is presented in this paper, where the authors also present a comprehensive analysis of the potential applications of the material.
Journal ArticleDOI
The composition, recycling and utilisation of Bayer red mud
TL;DR: In this article, different methods and techniques have been suggested for the consumption of bulk red mud to maintain a sustainable environment, and an appropriate costbenefit analysis of the existing technologies needs to be examined in the future because of the high cost of the transportation of a large amount of red mud from alumina refineries to the point of application.

The geopolymerisation of alumino-silicate minerals
Hua Xu,J.S.J. van Deventer +1 more
TL;DR: In this paper, the effect of mineral properties on the compressive strength of the synthesized geopolymer was investigated, and it was shown that a wide range of natural Al-Si minerals could serve as potential source materials for the synthesis of geopolymers.

Geopolymers and geopolymeric materials
TL;DR: In the last few years, a new generation of materials can polycondense just like organic polymers, at temperatures lower than 100 deg. C. This new generation, whether used pure, with fillers or reinforced, is already finding applications in all fields of industry as mentioned in this paper.
