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.

TL;DR: In this paper, a mechanistic model accounting for reduced structural reorganization and densification in the microstructure of geopolymer gels with high concentrations of soluble silicon in the activating solution has been proposed.

TL;DR: The microstructural evolution of alkali-activated binders based on blast furnace slag, fly ash and their blends during the first six months of sealed curing is assessed in this article.

TL;DR: The exact physicochemical nature of the geopolymeric binder phase has never before been determined as discussed by the authors, but it is known that it is composed of agglomerates of nanocrystalline zeolites compacted by an amorphous gel phase.

TL;DR: In the absence of an in-service track record comparable in scale and longevity to Portland cement, research is essential to validate durability testing methodology and improve geopolymer cement technology Colloid and interface science, gel chemistry, phase formation, reaction kinetics, transport phenomena, comminution, particle packing and rheology.
