Abstract:
The field of digital manufacturing (3-D printing) of concrete is rapidly evolving. An understanding of material properties and processing related parameters, and how they influence the properties of three-dimensional (3-D) printed structural components, is essential to ensure further advances in this nascent field. The proposed sessions will provide new information on selection of binder materials and combinations for successful 3-D printing; rheological characterization of cementitious materials as applied to digital manufacturing; the role of interfaces in the plastic and hardened stages; and microstructural architectures achievable by digital manufacturing to enable novel, multi-functional cementitious composites with special properties. This session will be valuable for researchers and students, and industrial entities interested in digital manufacturing and material processing.
