Evaluating the effects of porosity on the mechanical properties of extrusion-based 3D printed concrete

Elements fabricated by extrusion-based 3D concrete printing (3DCP) display anisotropic mechanical properties when subject to loading conditions orientated in principle cartesian axis directions. Various studies show that the mechanical characteristics of 3DCP components are lower than their mould-ca...
