TLDR
In this article, two types of powder-activated geopolymer binders having different proportions of fly ash and slag were used in comparison with OPC concrete for four different strength grades (40, 50, 65 and 80 MPa).About:

Mechanical and microstructural properties of high calcium fly ash one-part geopolymer cement made with granular activator.
TL;DR: The experimental findings showed that the resistance of one-part geopolymer cement paste increases with comparatively greater activator content, but raising the granular activator beyond 12 percent by fly ash weight decreases the strength and workability of the established one- part geopolym cement.

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
The greening of the concrete industry
TL;DR: The concrete industry is known to leave an enormous environmental footprint on Planet Earth as discussed by the authors, which contributes to the general appearance that concrete is not particularly environmentally friendly or compatible with the demands of sustainable development.
