Super compressible multifunctional metamaterial concrete

We demonstrate our striking vision towards developing a new generation of multifunctional concrete materials with unprecedented mechanical properties. The proposed “metamaterial concrete” is based on the integration of snapping metamaterial and concrete design concepts. We show how integrating the concrete mixture with auxetic polymer structures with snap-through buckling behavior results in creating a concrete material system with new functionalities. The developed proof-of-concept prototypes are experimentally tested to verify the efficient of the proposed concept. The results are in a reasonable agreement with the numerical simulations. We discuss the potential of the metamaterial concrete systems in revolutionizing the concrete construction via supplementing the inherent weaknesses of concrete in fatigue applications. The composite constituency of the metamaterial concrete shows levels of compressibility, while maintaining a high level of stiffness. The compressibility of this material reveals the future for a ductile concrete with significantly high flexural capacity and ability to absorb vibration without incurring any flaws.
