Alkali-activated binders: A review: Part 1. Historical background, terminology, reaction mechanisms and hydration products
TL;DR: Alkali-activated binders have emerged as an alternative to OPC binders, which seems to have superior durability and environmental impact as mentioned in this paper, and the proper terminology to designate these new binders will be discussed.
Journal ArticleDOI
Alkali-activated binders: A review. Part 2. About materials and binders manufacture
TL;DR: In this paper, the authors summarized current knowledge about alkali-activated binders, by reviewing previously published work, and suggested topics for future work in this field and theoretical questions are discussed.
Journal ArticleDOI
Synthesis and mechanical properties of metakaolinite-based geopolymer
TL;DR: In this article, the effect of concentration of NaOH solution on the mechanical and chemical properties of the metakaolinite-based geopolymer was investigated by means of X-ray diffraction, scanning electron microscopy (SEM) and infrared spectrometry (IR).

Geopolymerisation of multiple minerals
Hua Xu,Jannie S.J. van Deventer +1 more
TL;DR: In this article, three industrial materials, i.e., fly ash, kaolinite and albite, are selected to investigate various combinations. And the results show that when appropriate reaction parameters are used, the three component system gives geopolymers possessing the highest compressive strength and the lowest probability of cracking.
Journal ArticleDOI
Structure and properties of clay-based geopolymer cements: A review
TL;DR: In this article, the chemistry and structure of geopolymers, reaction mechanism and prime materials involved in geopolymer formation are discussed, and the characterization of geo-mers in terms of microstructural, crystallographic and functional groups is elucidated.

Geopolymers : inorganic polymeric new materials
TL;DR: In the last few years, technological progress has been made in the development of new materials such as "geopolymers" and new techniques, such as ''sol-gel'' as mentioned in this paper, opening up new applications and procedures and transforming ideas that have been taken for granted in inorganic chemistry.
Journal ArticleDOI
Location of Aluminum in Substituted Calcium Silicate Hydrate (C‐S‐H) Gels as Determined by 29Si and 27Al NMR and EELS
TL;DR: In this paper, the location of Al substituting in a semicrystalline C-S-H gel present in a hydrated synthetic slag glass was found to contain mainly pentameric silicate chains in which the central silicon is substituted by aluminum.
Journal ArticleDOI
Studies on blended Portland cements containing Santorin earth
TL;DR: In this paper, the pore refinement process associated with pozzolanic reactions plays an important part in enhancing the strength and chemical durability of portland Pozzolan cements.
