Abstract

In recent years, the rapid development of digital fabrication technology has substantially boosted the research of architected cellular materials. Among them, the auxetic materials are a distinct type for their unusual deformation behavior: negative Poisson’s ratio. When loaded longitudinally in compression, in contrast to conventional materials, the auxetic materials shrinks transversely, and vice versa. This featured deformation behavior gives the auxetic materials enhanced mechanical properties, especially high deformability and energy absorption ability. In many other fields, for instance metals and polymers, auxetic materials have already become a hot research topic. Numerous studies focusing on design, preparation, optimization, and application of auxetic materials have emerged. However, for cementitious materials, the auxetic behavior has never attracted attention and, to the author’s knowledge, auxetic cementitious cellular materials have never reported in literature. Therefore, this study mainly focuses on the development of architected cementitious cellular materials with auxetic behavior...
