Effect of the activator dose on the compressive strength and accelerated carbonation resistance of alkali silicate-activated slag/metakaolin blended materials [PDF]
, 2015 The effects of activator dose on the properties of alkali-activated slag/metakaolin blends, were studied in fresh and hardened states: heat evolution, strength and accelerated carbonation. High activator concentrations affect the slag dissolution rate,

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.. ABSTRACT Water and air pollution are pervasive issues, impacting the majority of global citizens. In response, geopolymers functionalized with photocatalytic metal oxides have emerged as sustainable materials for environmental remediation. This study examines how the Si/Al molar ratio (1 and 2) and photocatalytic WO3 loading (WO3/Al molar ratios of ...

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.

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.This study reports the fabrication of bio‐based 3D‐printed chitosan‐copper catalysts via masked stereolithography (MSLA). The resulting materials exhibit uniform metal distribution, good structural and thermal stability, and catalytic activity in the oxidation of biomass‐derived benzyl alcohol to benzaldehyde, demonstrating a sustainable and efficient ...
