Enhancing printability of 3D printed concrete by using metakaolin and silica fume
Structural Concrete, EarlyView.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.

A spring model for simulating the cracking process in RC members subjected to tensile actions
Structural Concrete, EarlyView.Abstract Predicting the development of cracking processes in structural elements made of reinforced concrete (RC) or other cementitious composites is still a challenging task. Although well‐established experimental procedures are widely adopted with the aim to gain empirical knowledge of the aforementioned processes, no similar consensus has been ...

Structural Concrete, EarlyView.Abstract The substitution of natural aggregates in concrete with recycled aggregates from construction waste makes ecological sense, is politically desired, and is increasingly being incorporated into technical regulations. Recycled concrete (RC) aggregates are also increasingly used for steel fiber reinforced concrete (SFRC) in the future. However, it
