Hollow concrete mimics human bones for 5x better toughness | Engineers have developed a new kind of concrete that promises more than 5 times the damage resistance of the usual stuff, by poking holes in its structure.

A pair of Princeton engineers have developed a new kind of concrete that promises more than 5 times the damage resistance of the usual stuff, by poking holes in its structure. For the new concrete, assistant professor of civil and environmental engineering Reza Moini and PhD candidate Shashank Gupta were inspired by the architecture of the dense outer shell of human thigh bones. The duo took cues from mother of pearl – found in crack-resistant oyster shells – which is made up of hexagonal tablets of aragonite joined by a biopolymer.
