Life cycle assessment of Hybrid alkali-activated cement production with red mud as an alkali activator

Environmental Science and Pollution Research, 2023
Abstract The production of Hybrid Alkali Activated Cement (HAAC) has generated considerable interest in environmental issues. In this research, the environmental impacts of utilizing red mud (RM) as a partial activator of alkali-activated ground granulated blast furnace slag (GBFS) in HAAC production have been evaluated. A contribution analysis

Internal Friction and Vulnerability of Mixed Alkali Glasses

, 2005
Based on a hopping model we show how the mixed alkali effect in glasses can be understood if only a small fraction c_V ofthe available sites for the mobile ions is vacant. In particular, we reproduce the peculiar behavior of the internal friction and the

Geopolymer Cement Based on Alkali Activated SlagGeopolymer Cement Based on Alkali Activated Slag

, 2021
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 .

Built‐In Interfacial Electric Field in Hydroxyl‐Terminated MXene/COF Heterostructures for Enhanced Solid‐State Supercapacitors

Advanced Functional Materials, EarlyView.
Hydroxyl‐terminated MXene is integrated with a redox‐active covalent organic framework through electrostatic self‐assembly followed by hydrothermal treatment to construct MXene/COF heterostructures with a built‐in interfacial electric field. Termination‐controlled interfacial electronic modulation induces charge redistribution and favorable band ...
