TL;DR: In this article, the authors reviewed the source, clean production and chemical compositions of ground granulated blast-furnace slag (GGBFS) and AAS-based concrete composites.

TL;DR: In this article, a review on the production of supplemental-cementing-materials (SCMs), their economic returns, environmental and durability impacts, the conceptual model for geopolymerization, durability affecting factors, and function and long-term durability properties of geocrete is presented.

TL;DR: In this article, a part of the cementitious material was replaced with constant high-volume fly ash, and a portion of fine aggregates was substituted by crumb rubber (CR), while adding silica fume (SF) was added, with the hope that by implementing a new type of nanomaterial, the loss in mechanical strength due to previous modifications such as rubberization and replacement will be prevented.

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.

TL;DR: In this paper, a comprehensive investigation of the crumb rubber incorporated ECC in terms of its compressive strength, flexural strength, direct tensile strength, and deflection abilities by adding crumbs rubber content as a replacement of fine aggregate, polyvinyl alcohol (PVA) and superplasticizers was performed.
