“…Rosewitz et al [28] brought this concept further and took inspiration from nacre, believing that it could lead to a new class of architected structural materials with superb mechanical properties. Bioinspired composites in their study were created by using 3D printed brick-and-mortar and auxetic polymer phases as reinforcement, cast in a conventional (albeit fine grained) mortar.…”

Additive manufacturing has been a topic of interest in the construction industry for the past decade. 3D printing of concrete structures promises great improvements in construction efficiency, waste reduction, and shape optimization. Another field where additive manufacturing offers opportunities is on the material level of cementitious composites. Techniques developed in other fields can be used to create multifunctional cementitious composites beyond what is possible with conventional technologies. This letter reviews recent developments in the field. Different applications are discussed: creating reinforcement for cementitious composites, creating capsules and vascular networks, and cementitious composites with superior mechanical behavior. Challenges for further research and practical applications of such materials are also discussed.

“…Rosewitz et al 3D-printed acrylonitrile butadiene (ABS)based mesh, with the geometry of individual unit cells ranging from reentrant, "bow-tie" to tubular structures, thereby exhibiting auxetic behavior i.e., Negative Poisson's ratio upon mechanical loading (Rosewitz et al, 2019). Auxetic behavior is observed by several living organisms in nature, for example in skin of salamander and also, in cat's skin, which exhibits out-ofplane auxetic behavior (Veronda and Westmann, 1970;Santulli and Langella, 2016).…”

Nature-inspired ensemble of organic and inorganic constituents, such as that found in the microstructure of nacre and dactyl clubs of Mantis shrimp, has evolved into the model system for the structural design of industrial composites. This novel design concept, which helps attaining the balance between strength, toughness and ductility, has not only induced a paradigm shift in the synthesis of advanced materials such as graphene-based composites but also, in the development of more abundant, low-cost materials such as cement and concretes. The advance in synthetic techniques and the advent of new manufacturing technologies such as 3D printing has enabled effective integration of cementitious materials with soft materials across various length scales. Furthermore, novel functional properties such as self-healing have also been materialized based on a variety of strategies. This review will provide the comprehensive overview on the ongoing research efforts, encompassing 3D printing, self-healing strategies and integration of C-S-H with organic components, all of which are actively exploited in synthesizing bioinspired, multifunctional cementitious materials.

“…fiber clustering. Rosewitz et al [33] used 3D printed bio-inspired polymeric structures as reinforcement for cement mortar to enhance the performance of cementitious material. These publications show that there is great potential in using additive manufacturing techniques for creating reinforcements which have potential to replace conventional fiber reinforcement.…”
