Abstract
This study explored the influence of air voids on the mechanical properties of 3D printed concrete. In particular, the impact of the size and position of the air voids were targeted by using three sizes of expanded polystyrene (EPS) beads strategically positioned at different locations within the printed samples, resulting in 12 types of printed bars. Consequently, mechanical samples were produced from the printed bars, and compression tests were carried out. The results of the study highlighted the importance of the size of defects, as small EPS bead sizes slightly impacted the compressive strength of the samples, while larger air voids significantly impacted the strength of the samples. Moreover, the findings of the study showed that the impact of the internally induced defects on the compressive strength of the samples was more significant than that of their counterparts placed at the filament interface.
