TL;DR: In this article, a fly ash microsphere (FAM) is used to reduce the internal friction between fly ash and slag grains and mitigate the agglomeration of flocs and fragmentation to release the locked water.

TL;DR: In this paper, the case of using fly ash and a local high-magnesium nickel slag (HMNS) as solid materials to manufacture geopolymer cement under the room temperature conditions was reported.

TL;DR: In this paper, the pore structure and shrinkage behavior of metakaolin-based geopolymer pastes and mortars containing 0-30% fly ash were investigated, and it was shown that fly ash substitution decreases average reactivity of the solid precursors, resulting in a lower reaction rate and accompanying longer reaction time.

TL;DR: In this article, the effects of high-magnesium nickel slag (HMNS) addition on the reaction, mechanical properties and microstructure of fly ash-based geopolymers are studied through isothermal conduction calorimetry (ICC), compressive strength testing, mercury intrusion porosimetry, scanning electron microscopy (SEM), X-ray diffractometry (XRD) and drying shrinkage testing.

TL;DR: In this paper, the properties and properties of fly ash and ground granulated blast furnace slag (GGBFS) blends were investigated via compressive strength testing, X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy/energy dispersive spectrography.
