Nowadays, additive manufacturing with cementitious mortar represents a promising technology in the construction industry. Currently, technical codes aiming to design structural capacity of 3D-printed walls are not available. In this study, the compressive strength of 3D printed cementitious hollow panels was experimentally investigated by means of monotonic uniaxial tests. The experimental outcomes were critically discussed with respect to base-material mechanical properties, geometric imperfections and aspect ratio. Brittle failure affected all the specimens. Damage level was strongly associated to thickness distribution along specimen height and material properties, whereas the aspect ratio had less significant influence.

Abstract
Nowadays, additive manufacturing with cementitious mortar represents a promising technology in the construction industry. Currently, technical codes aiming to design structural capacity of 3D-printed walls are not available. In this study, the compressive strength of 3D printed cementitious hollow panels was experimentally investigated by means of monotonic uniaxial tests. The experimental outcomes were critically discussed with respect to base-material mechanical properties, geometric imperfections and aspect ratio. Brittle failure affected all the specimens. Damage level was strongly associated to thickness distribution along specimen height and material properties, whereas the aspect ratio had less significant influence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
