Effect of adding acid solution on setting time and compressive strength of high calcium fly ash based geopolymer [PDF]
Fly ash with high calcium oxide content when used as the base material in geopolymer concrete could cause flash setting or rapid hardening. However, it might increase the compressive strength of geopolymer concrete.

Atomistic simulations of water‐driven structural and mechanical changes in N–A–S–H gels
Abstract This study employs molecular dynamics simulations to investigate the effect of varying water content (0–25 wt.%) and Si/Al ratio (1–3) on the atomistic structure and elastic properties of sodium aluminosilicate hydrates (N–A–S–H) gels. Results show that water molecules break the aluminosilicate framework by forming hydroxyl groups on AlO4 and ...

The Use of Borax in Deterring Flash Setting of High Calcium Fly Ash Based Geopolymer [PDF]
Geopolymer that was made with high CaO content fly ash was found to have higher compressive strength than the low CaO fly ash, using the same mixture composition.

Fayalite-Based Geopolymer Foam
The present work is the first study exploring the potential of geopolymer foams based on fayalite slag, an industrial by-product, as the primary precursor, for lightweight and fireproof construction applications. The research involved the synthesis and characterization of geopolymer foams with varying water to solid ratio, followed by testing their ...
