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.

Suppression Mechanisms for Cesium Leaching from a Fly Ash–Mixed Cement Matrix
JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.ABSTRACT The two suppression mechanisms for Cs leaching, which contain fly ash (FA), are the refinement effect on capillary pores and the adsorption effect that are dependent on the mix proportion of FA. If the leaching suppression by the adsorption effect is expected, FA should be mixed with the cement matrix at a replacement ratio of approximately 70
