Abstract
Three-dimensional concrete printing (3DCP) is increasingly being applied in harsh environments and isolated regions. However, the effective utilization of aeolian sand (AS) resources and by-products derived from arid zones for 3DCP is yet to be fully realized. This study developed a three-dimensional (3D) printing composite using AS and magnesium oxychloride cement (MOC) from local materials. The effects of the mole ratio of MgO/MgCl2 and sand/binder (S/B) ratio on the mechanical properties such as water resistance, drying shrinkage strain, rheology, and printability, were investigated systematically. The results indicated that the optimal mole ratio of MgO/MgCl2 was 8, which yielded the desired mechanical performance and water resistance. Furthermore, the S/B ratio can be increased to three within the desired printability to increase the AS utilization rate. The rheological recovery and buildability of the 3D-printed MOC with AS were verified. These findings provide a promising strategy for construction in remote deserts.
