Princeton engineers have created a cement-based material that is 5.6 times more damage-resistant, inspired by the structure of human bone.

Tubular design, like the one found in our thigh bones, has the power to make cement tougher without using any reinforcing material.Researchers at the University of Princeton have developed a cement paste that is 5.6 times stronger than cement, mortar, and other conventional cement-based construction materials.

A building made with material with poor toughness can collapse suddenly, causing severe damage to property and human lives. Inspired by the tubular structure of cortical bone, the researchers developed a cement paste featuring cylindrical and elliptical tubes. These tubular structures improved the crack-resistant properties of the cement, similar to how osteons strengthen the femur.
