A Comparison Study for Chloride-Binding Capacity between Alkali-Activated Fly Ash and Slag in the Use of Seawater [PDF]

open access: yes, 2017
This study aimed to investigate the chloride-binding capacity of alkali-activated fly ash (denoted as FSW) and slag (denoted as SSW) samples and their synthesized Cl-bearing phases, which are capable of binding and immobilizing chloride when seawater is ...

Effect of Carbonation on Alkali‐Activated Slag Paste

open access: yesJournal of the American Ceramic Society, 2006
Carbonation on waterglass‐ and NaOH‐activated slag pastes was analyzed and compared with carbonation in Portland cement pastes to determine possible differences. Thermogravimetry‐differential thermal analysis (TG/DTA), Fourier‐transform infrared spectrometry, and nuclear magnetic resonance were used to ...

Geopolymer Cement Based on Alkali Activated Slag [PDF]

open access: yesJournal of Scientific Research in Science, 2018
The aim of this investigation is to prepare  geopolymer cement by mixing various amounts of granulated blast furnace slag (GBFS) with Fly ash (FA) and  cement kiln dust (CKD).  Seven blends  are  prepared  using 100 %  slag , 95% slag+5% CKD or fly ash ,  90% slag + 10% CKD or Fly ash  and  85% slag + 15% CKD or Fly ash .

Synergistic Cu‐Zn/Fly Ash Catalysts for Intensified Sorption‐Enhanced CO2 Hydrogenation to CO Through the RWGS Reaction

open access: yesChemCatChem, Volume 18, Issue 2, 28 January 2026.
Sorption‐enhanced reverse water–gas shift (SERWGS) enables efficient CO2‐to‐CO conversion. The developed catalyst (15Cu‐7.5 Zn/FANa‐H) significantly improves CO2 conversion to CO, exceeding the thermodynamic equilibrium limit and demonstrating its potential for intensified syngas production through in situ adsorption of water using a hydrophilic ...

Phase diagrams for alkali-activated slag binders [PDF]

open access: yesCement and Concrete Research, 2017
Phase diagrams for alkali-activated slag (AAS) binders are simulated at (metastable) thermodynamic equilibrium, spanning the relevant compositional envelopes for these materials. The phase diagrams are generally consistent with experimental observations in the literature, dominated by calcium (alkali) aluminosilicate hydrate (C-(N-)A-S-H) gels and Mg ...

Recycling of Spent Cathode Carbon from Aluminum Electrolysis: Detoxification Approaches, Resource Utilization, and Environmental Perspectives

open access: yesChemElectroChem, Volume 13, Issue 1, January 2026.
This review outlines the recycling of spent cathode carbon from aluminum electrolysis. Detoxification strategies, including molten salt roasting and ultrasonic‐assisted leaching, are depicted as effective approaches for removing hazardous components. The recovered carbon is further directed toward resource utilization, such as in lithium‐ and carbon ...
