Alkali-activated materials: the role of molecular-scale research and lessons from the energy transition to combat climate change

open access: yesRILEM Technical Letters, 2020
Alternative (i.e., non-Portland) cements, such as alkali-activated materials, have gained significant interest from the scientific community due to their proven CO2 savings compared with Portland cement together with known short-term performance ...

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 .

Creep Differences Between Alkali-Activated Fly Ash–Slag and Cement-Based Materials and Prediction Models

open access: yesBuildings
Alkali-activated fly ash and slag binders are regarded as environmentally friendly building materials. However, the creep properties of the alkali-activated materials differ from ordinary Portland cement-based materials.

3D printed alkali activated cement strain sensors

open access: yes, 2021
Concrete degradation is a significant challenge for asset managers, who are struggling to balance the need for monitoring and maintenance with the high costs and risks of manually deploying sensor and repair technologies. This paper presents 3D printed strain sensors based on alkali activated cement repairs, demonstrating a fixed-cost method for ...

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.
