3D Printing Concrete on temporary surfaces: The design and fabrication of a concrete shell structure [PDF]

Automation in Construction, 2018
One of the geometrical restrictions associated with printed paste materials such as concrete, is that material must be self-supporting during printing. In this research paper a new methodology for 3D Printing Concrete onto a temporary freeform surface is presented. This is achieved by setting up a workflow for combining a Flexible Mould developed at TU

A method for evaluating the printability of concrete in 3D-printed pavement. [PDF]

MethodsX
The purpose of this study is to address the limitation that quality control methods of pavement concrete do not account for the printability evaluation of 3D printed pavement concrete. Based on the edge slump test, shape-holding strength test and surface smoothness test, the graded evaluation indicators for the printability of 3D printed pavement ...

Microstructural examination of carbonated 3D‐printed concrete [PDF]

Journal of Microscopy, 2022
AbstractThe recent interest in 3D printing with concrete has generated great interest on how inhomogeneities arise and affect performance parameters, in particular strength and durability. With respect to durability, of particular interest is how 3D‐printed layer interfaces can impact transport of species of interest, such as moisture, chlorides or ...

Characterizing the bond properties of automatically placed helical reinforcement in 3D printed concrete [PDF]

, 2022
The incompatibility of 3D concrete printing (3DCP) with conventional reinforcement methods is well known. Recently, solutions have suggested the insertion of helical reinforcement rods through a screwing motion into the freshly printed material.

3D Printing Concrete: A Review

IOP Conference Series: Materials Science and Engineering, 2021
Abstract 3D Printing concrete is new developed technology with no reinforcement or by providing reinforcement as like cable in the year 1987. The printing concrete is printed with the printer in different shapes and sizes. Size of aggregate used is very minimum which passes through the nozzle of printer. The strength of 3DPC is tested by
