Large-scale 3D printing of ultra-high performance concrete – a new processing route for architects and builders
Clément Gosselin,Romain Duballet,Philippe Roux,Nadja Gaudillière,Justin Dirrenberger,Philippe-H. Morel +5 more
TL;DR: In this article, a new additive manufacturing processing route is introduced for ultra-high performance concrete, in which a material is deposited layer by layer through an extrusion printhead mounted on a 6-axis robotic arm.
Journal ArticleDOI
A critical review of the use of 3-D printing in the construction industry
Peng Wu,Jun Wang,Xiangyu Wang +2 more
TL;DR: In this paper, a systematic review shows that 3-D printing technology, after years of evolution, can be used to print large-scale architectural models and buildings, however, the potential of the technology is limited by the lack of large scale implementation, the development of building information modeling, the requirements of mass customization, and the life cycle cost of the printed projects.
Journal ArticleDOI
Structural built-up of cement-based materials used for 3D-printing extrusion techniques
TL;DR: In this paper, the authors investigated the role of the structural build-up properties of concrete and cement-based materials in a layer-by-layer construction technique and proposed a theoretical framework to optimize the building rate.

Self-Compacting Concrete
Hajime Okamura,Masahiro Ouchi +1 more
TL;DR: Ozawa and Maekawa as mentioned in this paper developed a self-compacting concrete, which can be compacted into every corner of a formwork, purely by means of its own weight and with out the need for vibrating compaction.

Influence of key parameters on drying shrinkage of cementitious materials
TL;DR: In this paper, a study performed to evaluate the deformation of concrete structures under drying conditions was presented, and the results indicated that between 48 and 100% relative humidity, the shrinkage of cement paste is approximately inversely proportional to relative humidity.
