Geopolymer

TL;DR: In this article, the properties of pervious concrete made of high-calcium fly ash geopolymer binder were evaluated and the relationship of the density-void content, compressive strength-density, and compressive-strength void content of the PGCs were derived and found to be similar to those of conventional concrete.

TL;DR: In this paper, the amorphous components of fly ash are the reactive components in the geopolymerization reaction and this information is used to synthesize metakaolin geopolymers with the same targeted composition.

TL;DR: In this article, the authors investigated the durability and microstructure of fly ash and metakaolin-based geopolymer exposed to elevated temperatures and acid attack and found that the densities of the pore structures of the fly ash-metakaolin mixture are higher than those of OPC.

TL;DR: The influence of preliminary calcination of fly ashes on the geopolymerisation process has been studied and the decrease in compressive strength of the geopolicmers is discussed in terms of partial surface crystallisation of the fly ash particles.

TL;DR: In this article, the durability and leaching behavior of MT-based geopolymer bricks are studied by measuring unconfined compression strength (UCS), water absorption, weight loss, and concentration of heavy metals after immersion in pH = 4 and 7 solutions for different periods of time.
