Özet

The biggest obstacle to become widespread 3D Printing Concrete (3DPC) is the insufficient interlayer-bonding strength (IBS). The parameters affecting the IBS are classified as physical effects such as cleanliness and roughness, effects caused by the material properties it contains, and printer-induced effects for instance interlayer interval time, nozzle shape and printing speed. However, it was stated that the rheological properties of 3DPC mixtures should also be examined in order to strengthen the IBS. In this article, the relationship between IBS and rheological properties of 3DPC mixtures is discussed. It was stated that the static yield stress and the structural build-up have an optimum value in terms of the effect on IBS of 3DPC mixtures. On the other hand, studies indicating that the IBS of 3DPC mixtures depends on surface moisture of the layers were also encountered.
