Abstract:
Additive manufacturing of cementitious materials has a great potential for enlarging the freedom of form of concrete structures. This next-generation technology opens up a new possibility – cementitious metamaterial – which possesses unique properties that cannot be achieved from inherent properties of concrete. The internal shape, size, and geometry of the material is engineered at mm-cm scales, which enables an auxetic behavior, strain-hardening behavior, etc. This study presents a computational design method that heuristically generates the internal design of a cement-based material for achieving desired mechanical properties.
