Abstract
This comprehensive study explores the transformative advancements in large-scale 3-D printing within the realm of concrete construction. Investigating the mechanical behavior and design considerations of 3-D printed structures, the research addresses challenges, proposes design perspectives, and provides structural insights. Mechanical characterization of 3-D printed elements reveals weaker and more porous interfaces, impacting axial compression, out-of-plane flexure, and shear. The study establishes design guidelines by drawing comparisons with traditional concrete structures. Additionally, it delves into the rheological model of cement paste, considering shear rate conditions and thermodynamics-based improvements. The research extends to a comparison between 3-D printed blocks and Autoclaved Aerated Concrete blocks, analyzing properties, costs, and environmental concerns. In conclusion, this study offers valuable insights for architects, engineers, and stakeholders in navigating the evolving landscape of large-scale 3-D printing in concrete construction.
