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

Buildings
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.

The influence of curing temperature on the strength and phase assemblage of hybrid cements based on GGBFS/FA blends

Frontiers in Materials, 2022
Hybrid cements are composites made of Portland cement or Portland clinker and one or more supplementary cementitious materials like slag, fly ash or metakaolin, activated with an alkali salt.

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other

Batteries From Reused, Recycled, and Surplus Materials

Advanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Alkali-activated metallurgical slag as a sustainable adsorbent

Bulletin of the Karaganda University. "Chemistry" series, 2021
This paper is devoted to obtaining a zeolite-containing sorbent based on metallurgical waste — slag. The synthesis of zeolite adsorbent from ash and slag was carried out by hydrochemical and thermal treatment. The initial object and the obtained material were characterized using following methods: Fourier-transform infrared spectroscopy, scanning ...

Pedogeomorphology of semiarid soils of Ulu Peninsula, James Ross Island, Antarctica

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Located in a transitional climatic zone of the Antarctic continent, James Ross Island (JRI) presents soils that reflect complex interactions between lithology, topography, and pedogenesis. This study characterizes soils along a toposequence to evaluate how slope position and parent material control soil properties and weathering patterns in a ...

Effects of three different types of fibers and dosage on the properties of alkali-activated copper slag–slag cementitious materials

Scientific Reports
The use of copper slag instead of part of the slag to prepare alkali-activated cementitious materials can achieve the resource utilisation of copper slag, but alkali-activated copper slag–slag composite cementitious materials have the disadvantages of ...
