Shell-inspired cement is super stretchy, crack-resistant and unbreakable

by

Inspired by the materials found in oyster and abalone shells, researchers at Princeton University have created a new, highly versatile cement composite. This design mimics the physical structure of the shell and improves durability by promoting inelastic deformation and hierarchical strengthening. The newly developed material is 19 times more flexible, can stretch without breaking and … Read more
