Enhancing printability of 3D printed concrete by using metakaolin and silica fume

open access: yesStructural 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.
