Abstract
3D concrete printing (3DCP) offers efficiency and design flexibility. However, it raises sustainability concerns due to increased cement consumption. This study investigates the combined effects of MgO replacement (25% and 50%) and carbonated water on the performance of 3DCP. Results show that the combined effect of MgO and carbonated water yields the highest improvement in static yield strength. Compressive strength increases with 25% MgO replacement, while it decreases at 50%. Carbonated water slightly enhances strength across all mixes. The findings highlight 25% MgO as the optimal replacement, considering static yield stress and compressive strength b
