Effect of vibration on yield stress of concrete for 3D printing applications
Concrete 3D printing is one of the latest developments in the field of construction. It promises several benefits but needs further development before it can be used as a practical construction technique. One primary challenge is the requirement for 3D printable concrete to behave like a fluid …

Implementing Continuous Fiber Reinforcement for Concrete Additive Manufacturing
Concrete additive manufacturing is a promising alternative to standard concrete construction, but the inability to print reinforcement as part of the manufacturing process is a significant limitation. This thesis proposes a method of extruding continuous fiber reinforcement during the 3D printing …

Mix design and testing improvements for 3D printable concrete mixtures with fibers
Vertical concrete construction primarily relies on formwork filled with a flowable concrete mixture. This is simple and effective, but formwork is costly. There has been a recent body of research and small industry in vertical concrete construction using a filament 3D printing technique for small …

Hold up : machine delay in architectural design
… of the science and practice of curing in concrete fabrication. The second part of this paper is dedicated to the introduction of Machine Delay Fabrication. The foundational concept of MDFab, machine delay, is introduced. The conceptual design implications of MDFab are discussed. The method …

High-performance carbonatable cementitious systems: novel materials and processing methods
… becomes more pronounced in large-scale concrete members that may require longer carbonation time and higher CO2 pressures. CCMs with enzymatic solution-impregnated hydrogels in the presence of external CO2 have better mechanical (up to 80% improvement compared to control CCMs) and …

Fiber Orientation Effects on the Fracture and Flexural Toughness of Extruded Fiber Reinforced Concrete for Additive Manufacturing
… ductility and post-peak behavior are achieved in concrete to which fibers have been added, as has been demonstrated in other studies, although this study further demonstrated how preferential fiber alignment produced via an extrusion can enhance fracture and flexural properties of cementitious …

Rheology of cement-based materials used for large-scale 3D printing
L'impression 3D béton introduit une toute nouvelle technique de production d'éléments en béton. Les avantages de cette technique par rapport à la méthode de construction conventionnelle basée sur l’utilisation de coffrage sont (1) une production plus facile et moins coûteuse des éléments à …
