"3D Printed Concrete (3DPC) is a developing method of construction that has advantages over conventional methods, including formwork reduction, complex geometry, and expedited construction. This technology has potential benefits for the military when considering the austere environments that forward operating bases are built in. This study aims to assess 3DPC applications in protective structures that protect critical assets from explosive blasts. These protective structures experience a high-strain rate response during blast loading of the structure, and the effects of this have yet to be analyzed in the literature concerning 3DPC. With the lack of prior research, the focus here will be on blast testing unreinforced samples. In addition, past literature has established that 3DPC has inherent issues in adhesion between layers. When subjected to high-strain rate tests, the interfacial adhesion was weaker than in low-strain rate applications. The goal of this research was to do an initial assessment of the effect of interfacial adhesion between layers on the overall strength of the 3DPC during blast loading. The research showed that when subjected to identical strain rates, 3DPC had substantially higher deflections than predicted, while conventionally cast concrete samples experienced significantly less deflection and showed no damage. This study suggests that understanding lack-of-fusion and reinforcement considerations can benefit the high-strain rate response of 3DPC"--Abstract, p. iii
