Provoked by recent advancements in additive manufacturing, 3D printable concrete has been explored as an alternative method to construct concrete structures. 3D printing of cementitious materials has the potential to address several major challenges faced by the current concrete industry: (i) it eliminates the use of formwork (mold) and vibration that are typically necessary for consolidating wet concrete, which can in turn significantly reduce material and labor costs involved in the formwork construction; (ii) the highly automated construction process can reduce the material waste, cut down construction time, and reduce human error; in addition, (iii) it allows a new approach for concrete design–the composition and property of printed material can be parametrically varied from one location to another, tuning to the optimal structural performance and functionalities. In the last decade, some showcase examples have became available–e.g., WinSun, XTree, TotalKustom, Smart Dynamic Concrete, as this new construction technology becomes more commercially and economically feasible.

Developing 3D Printable Functional Cementitious Composite

Due to challenges with COVID-19, this 17th Biennial has been moved to April 2021 and will now be offered in a virtual format. This conference aims to bring the experience and knowledge of experts in the aerospace industry together to share and discuss the latest research and engineering techniques that effect the exploration and settlement of space. Presentations will be made in multiple concurrent symposia over three days. Topics will include: Granular materials in space exploration, Exploration in utilization of extra-terrestrial bodies, advanced materials and designs for aerospace and terrestrial structures under extreme environment, Structures in challenging environments, and Space engineering, construction, and architecture for Moon, Mars, and beyond.
