A novel method to enhance the interlayer bonding of 3D printing concrete: An experimental and computational investigation
Abstract
Abstract This study focuses on one of the bottlenecks facing the concrete 3D printing technology, the lack of proper bonding between the two adjacent layers of 3D printed concrete. Herein, a new polymer consisting of black carbon and sulfur was used to glue the two layers together. The experimental results, verified via molecular dynamics and density functional theory calculations, showed a considerable increase in the interlayer bonding strength. Two-fold rise in interlayer tensile strength as well as chemical cohesion depicted by scanning electron microscopy proves this approach to be successful in providing enhanced bonding between two adjacent printed mortar layers without hindering the printing process. The improvement arises from different types of forces in the interlayer region of modified samples, compared to that of the interlayer region of original sample. The uniform surface provided by the hardened polymer is a good substrate for the top layer in addition to extending the time gap between printing layers. This novel method can accelerate the automation of the construction industry, while reducing the costs in terms of both human labor and capital.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
