Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.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.

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.ABSTRACT The use of laterite soil with high Al and Fe content has been investigated as a novel supplementary cementitious material (SCM) to replace traditional mineral materials for clinker substitution. High‐energy ball milling was used to mechanochemically activate laterite and change its reactivity.

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.ABSTRACT Hydration temperature and particle size strongly influence the reaction kinetics of supplementary cementitious materials (SCMs). This study focuses on quantifying and modeling these effects on ground granulated blast furnace slag (GGBFS) hydration in the R3 model system.

Enhancing printability of 3D printed concrete by using metakaolin and silica fume
Structural Concrete, Volume 27, Issue 1, Page 1068-1084, February 2026.Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Quantitative disentanglement of nanocrystalline phases in cement pastes by synchrotron ptychographic X-ray tomography [PDF]
, 2019 Mortars and concretes are ubiquitous materials with very complex hierarchical microstructures. To fully understand their main properties and to decrease their CO2 footprint, a sound description of their spatially resolved mineralogy is necessary ...
