Creep Behaviour of Fly Ash-Based Geopolymer Concrete

Civil Engineering Dimension, 2010
Fly ash-based geopolymer concrete is manufactured using fly ash as its source material and does not use Portland cement at all. Beside fly ash, alkaline solution is also utilized to make geopolymer paste which binds the aggregates to form geopolymer ...

Phase Transformations, Microstructural Effects, and Photocatalytic Activity of Tungsten Trioxide‐Geopolymer Composites

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 ...

Reactivity Evolution of Mechanochemically Activated Laterite Used as a Supplementary Cementitious Material

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.
