Abstract 3D printed concrete structures often exhibit considerable degree of anisotropy and
inhomogeneity because of layered material deposition and inferior properties of the …

In this work, a novel theoretical model of the void length probability distribution in 3D printed
concrete is established based on a zigzag analog of the layer interface. A quasi-exponential …

Past experimental results have shown that the use of nozzle trowels can enhance the
interlayer strength of 3D printed cement paste. In this study, the design is further optimized …

The field of 3D printing is in rapid evolution. The 3D printing technology applied to civil
engineering is a promising advancement. From equipment and mixture design to testing …

Abstract 3D printed concrete is an emerging intelligent construction method, and it has been
attracting an exponential attention in this sector. However, one of the major issues in printed …

Various flow directions are employed in the actual printing process, resulting in different
printed results. This study primarily investigates how flow direction impacts the distribution of …

In 3D concrete printing, layer interface and interlayer notch are generated by the layer-by-
layer process. Therefore, the 3D printed concrete is anisotropic with the interlayer strength …

In order to address the dual objectives of enhancing the mechanical and thermal
performance of 3D printed concrete, this paper presents a 3D printing approach to design …

This experimental study analyses coarse aggregate-containing and coarse aggregate-free
materials from the perspective of additive manufacturing. The primary objective is to identify …

Depositing of printing layer on the previous printed structures leads to the formation of
contact surface forces between two layers. However, it is not clear how do the contact …
