Abstract
The interest and knowledge in the research field of 3D concrete printing are vastly increasing. With the rise of more established printing methods and materials, larger elements with a higher degree of geometric complexity can be printed. This allows to shift the research focus towards the structural application of 3D printed concrete. The need for numerical modelling of these printed structures arises, wherein insight into the elastic properties of the material is essential. Multiple sources report about a certain degree of anisotropic behavior in the failure state, but researchers fail to reach a consensus concerning the degree of anisotropy in the elastic range in the hardened state of the homogenized material. During an exploratory experimental study, the directional dependency of cylindrical printed specimens is investigated based on uniaxial compression tests and optical displacement measurements. Cast cylinders and 3D printed cylinders in two different orientations are compared. Quasi-static moduli of elasticity are quantified in accordance with the concrete standard EN 12390-13, after which a preliminary conclusion concerning the degree of anisotropy of 3D printed concrete is presented.With this information, a new step is taken towards the numerical modelling of 3D printed concrete in order to use it for structural applications.
